(at around 1h 11 mins) When in the back of the taxi, Butch takes his boxing gloves off and then throws them out the window. When he throws them out you can hear them hit the ground perfectly as if they weren't in a moving car and just parked.
(at around 53 mins) When Mia finds the bag of heroin in Vincent's coat, she states, "Hello." A second dubbed "hello" can clearly be heard under the first, possibly due to original dialogue not after an ADR take was added.
(at around 2h 10 mins) When Winston Wolf departs from Monster Joe's in his Acura, he takes a hard corner, but the sound indicates continuous acceleration in a straight line. While the acceleration is possible, it would sound different going around a corner.
(at around 1h 30 mins) After shooting Vincent, Butch pushes the bloody door open with his fingertips (thus leaving bloody fingerprints). He then proceeds to wipe only one side of Vincent's gun with clean hands, despite never washing them.
(at around 15 mins) The amount of Brett's burger that has been eaten as Jules picks it up. Also, the burger itself changes between shots: when Jules picks it up it looks like a simple cheeseburger, then lettuce appears on the bottom of the burger once he takes a bite.
(at around 52 mins) After getting back from Jack Rabbit Slim's, Mia has Vincent's coat on. When she is about to light herself a cigarette, she isn't wearing it, but when she reaches for the lighter, she is wearing it again.
(at around 58 mins) When Jody comes out of the room Lance has been in looking for the medical manual, she does not have any of her jewelry piercings in her face. A few moments later when they're about to give Mia the adrenaline shot, the jewelry has appeared on her face.
(at around 2h 10 mins) When Jules and Vincent are in the Hawthorne Grill diner at the end of the movie, the ice in their water glasses changes. At one point, it's completely melted. Seconds later, ice reappears in the glasses.
(at around 1h 50 mins) After Jules shoots Brett, he clearly empties his clip as the gun retracts. However, later as the scene continues, after the guy from the back fails to shoot Jules and Vincent, Jule's gun is loaded again as he fires back.
(at around 1h 2 mins) When Vincent and Mia are talking outside her house, Mia's arms change position between shots. When seen from the front she holds her arms or has them crossed, when seen from behind her arms are beside her body.
(at around 1h 45 mins) In the dungeon scene where the two perverts, Maynard and Zed, are raping Marsellus, Butch comes in to rescue Marsellus and finds a sword. When Butch goes downstairs to the dungeon, Marsellus is hog tied with gag ball in his mouth getting defiled. Butch kills Maynard, with the sword and is about to kill Zed. Marsellus now gets up having miraculously freed himself without Butch cutting him loose. How could Marsellus suddenly get up from being hog tied before Butch, occupied with killing Maynard, could free him?
(at around 1h 45 mins) When Butch jumps on Zed's chopper in front of Maynard's store, a two-barreled carburetor can be clearly seen protruding from behind the air cleaner cover on the motorcycle. When Butch pulls up in front of the motel to pick up Fabienne, the two-barreled carburetor is missing.
(at around 56 mins) At the end of Vincent's phone call, (when Lance exclaims "PRANK CALLER" twice), he has a cigarette in his right hand. Facing the window in the next cut, as the car rolls past and Lance throws his hands up, the cigarette is gone.

(at around 1h) After Mia regains consciousness from the adrenaline shot, her hand changes position from hovering near the syringe stuck in her chest to being on the floor in the next shot and then rising to hover near the syringe.
(at around 2h 10 mins) When they are at Monster Joe's used auto parts, The Wolf is walking to his car, and there are 4 vehicles parked on the left - a truck, a yellow VW bug, a 2nd truck, and another car. But when The Wolf gets in his car and jets off, the 2 vehicles behind the VW are replaced by 2 other vehicles parked further away.
(at around 1h 45 mins) In the basement after Butch kills Maynard he holds the sword behind him, there's a quick cut where he holds the sword to Zed's throat but then after the next cut Butch again holds the sword behind him.
Around 2h 15min When Vincent and Jules talking about dog as a filthy animal Vincent when waitress brings Vincent his pancakes and bacon. He's still spreading butter on his pancakes and not eating yet and then stops, starts laughing at Jules joke (both Jules and Vincent shown) but when camera immediately focuses on Vincent he's now chewing something. There's no way he could've put food in his mouth that quickly while already laughing.
(at around 1h 35 mins) While Butch is pointing the gun at Marsellus and is about to shoot him inside Maynard's store, his right hand changes in a quick cutaway with the fingers pointing in the opposite direction.
(at around 34 mins) Mia's bangs change while she's talking to Ed Sullivan at Jack Rabbit Slim's. There are less of them when she first talks to him. When the camera looks at her again, her bangs are full.

(at around 1h 15 mins) In the "gold Watch" scene, Butch gets out of the cab, then it cuts to Butch paying Esmarelda Villalobos. When the view returns to the whole cab again, you can tell the cab is moved back from when they first arrived.
(at around 32 mins) When Vincent enters Mia's home for the first time, a camera and a camera operator are clearly visible in a reflection on the windows in front of them. They have a black blanket or tarp covering them to make them harder to see.
(at around 1h 50 mins) During the Bonnie Situation scene where the guy comes out of the bathroom and fires and misses his entire load at Vincent and Jules, you can clearly see the two squibs on his chest under his sweatshirt, where he is going to be shot.

(at around 2h 10 mins) When Winston tells Jules and Vincent the route that they'll be taking from Jimmy's house in Toluca Lake to Monster Joe's in North Hollywood, he says they'll be going up Hollywood Way. Hollywood Way is to the east of both Toluca Lake and North Hollywood, it wouldn't make sense for them to go that way, especially if they want to spend as little time on the streets as possible.
(at around 1h 5 mins) Capt. Koons' account of Butch's grandfather, Dane Coolidge, contains historical inaccuracies. Koons says Dane Coolidge was called up to fight the Germans in WWII as a Marine and later says Dane was killed at the Battle of Wake Island. Very few US Marines fought against the Germans in WWII. Marines mostly fought in the Pacific against the Japanese which is where Wake Island is. He also says that Dane gave the watch to a gunner on an Air Force transport. The U.S. Air Force wasn't created until after WWII. At that time it would have been called the U.S. Army Air Corps. Transports were also typically unarmed and would not have gunners.
(at around 1h 30 mins) When Butch opens the door of the Apt/Condo with a Brass Kwikset key, he turns the key clockwise, which in fact would actually lock the doorknob. Turning it counter clockwise unlocks a Kwikset entry lockset.
(Around 1h 16m)
Butch pulls a shirt over his head while smoking a cigarette. The cigarette would have likely singed the shirt or become bent as the shirt moved over it, yet it is shown still in Butch's mouth in perfect condition after the fact. Even if Butch took the cigarette out of his mouth, he could not have put the shirt on with one hand.
In the beginning diner scene when Yolanda and Ringo are about to rob the place, Yolanda yells "...and I'll execute every motherfucking last one of you". At the ending diner scene (which should be the exact same), she yells "...and I'll execute every one of you motherfuckers". This is to show different perceptions of the same event. The first being Yolanda's and Ringo's and the last being Jules'
(at around 1h 12 mins) In the taxi, Butch throws his boxing clothes out a fully-open window, and Esmarelda tosses a butt out her open window. The squealing tires, near-miss as she leaves the alley, and background indicate she's driving fast. But as Butch smokes the cigarette, its smoke drifts slowly through the car, indicating it isn't moving because no wind is coming through the open windows. However, the back projection is heavily stylized in black & white, so the director clearly did not intend this to be a realistic shot. Although the shot may have been intentionally unrealistic, when Butch throws his gloves out the window a "plop" can be clearly heard, indicating no vehicle movement.
Jules purports to quote the Bible several times in the film ("Ezekiel 25:17"). In reality only the final line of this recitation is correct for this Scripture reference, so each time it is a misquote. Tarantino stated that this was intentional to give insight into the character's psychology.
At one point, Vincent says, "I don't watch TV." Later, he mentions something he once saw on the television show Cops. The phrase "I don't watch TV" generally means that the speaker does not make a habit of watching television. It generally does not mean that the speaker avoids television completely and has never seen a single episode of any show ever. Most people who "don't watch TV" will watch TV from time to time, depending on the situation at hand. Vincent seems to be no exception.
Whenever the two shots from inside the apartment are shown, they are shown in different perspectives, so it might be that all goofs spotted in the two apartment scenes can be considered as being different characters in the movie perceiving things differently.
(at around 1h 50 mins) In the apartment miracle scene where Jules and Vincent are about to be shot at by the kid in coming out of the adjoining room, there are bullet holes already clearly visible in the wall behind them.
(at around 1h 22 mins) In the Gold Watch scene, when Fabienne's reflection is shown in the motel room TV screen, it is a full body reflection. The TV is too high, and she is too close to it for that to be possible.
(at around 56 mins) When Vincent Vega drives up to the house with Mia Wallace and crashes, you can see tire tracks in the grass where the original car continued through out of shot so when the camera tracks around it shows only the placed car.
In the final diner scene, before Jules puts his wallet in the bag, it is so thick with bills it looks like it would spring open and it couldn't possibly have been in his pocket, and yet when pumpkin pulls it out of the bag a minute later it is suddenly thin.
(at around 18 mins) In the Big Kahuna Burger scene, when Jules shoots the guy lying down his gun shows no muzzle flash, but when Brett is shot, both Jules' and Vincent's gun show very clear muzzle flashes.
(Deleted scene) When Mia interviews Vincent on the video camera, the perspective of the video camera (and Mia) keep moving, but the cutaways to Mia holding the camera are the same, being stationary with the same background.
When in the beginning where Vincent and Jules are in the apartment after shooting Bret the guy comes out of the bathroom and shoots at Vincent and Jules. If you noticed before the the shots are fired there are already bullet holes in the wall.
(at around 1h 55 mins) After washing his hands at Jimmie's, Jules dries off with a towel and then places the towel on a rack. After a few moments the towel slips and falls off the rack. There is no sound effect and neither character seems to notice.
The goof items below may give away important plot points.
(at around 1h) When Mia overdoses and is taken to Lance's apartment, a dot is drawn on her chest to show Vincent where he will be stabbing her with the adrenaline shot. After she gets up, the dot is gone.
(at around 1h 50 mins) When Butch is picking up Fabienne with the chopper from Zed and he is outside waiting for her, the front light of the chopper is switched off and on in different cuts of the scene.
(at around 1h 35 mins) Errors when Marsellus and Butch are trapped inside Maynard's basement: 1) When he starts sprinkling water to wake them up, Butch is seen bent further down in the back shot. 2) Maynard then sprays them upwards, but in the next shot the water is coming downwards. 3) When Maynard finishes sprinkling, Butch turns to Marsellus, but in the next shot he is facing away. 4) When Maynard goes upstairs to open the door for Zed, Marsellus's shirt is untucked covering his crotch and Butch's blood stain on his shirt looks darker. In the next shot, Marsellus's shirt has changed as well as the blood stain on Butch's shirt, which looks lighter. After Zed walks in, the shirt and the stain change back.
(at around 1h 30 mins) In the "gold watch" scene, when Butch grabs his watch he turns left out of his room into the kitchen. When he shoots Vega you can see that his room is on the right hand side, you can see the kangaroo where his watch was, but after he looks at Vega's body he takes a left into his room which is now the living room where he exits the apartment.
When Jules executes Brett for the first time on screen, he fires his pistol until empty (you can see the slide stop). The second time, in the miracle scene, his pistol still has ammunition left after executing Brett (no slide stop).
(at around 1h 55 mins) When Vincent shoots Marvin, the bullet goes through his head causing blood to cover the rear window. From that range, the bullet would have gone through the window as well, which it did not.
