Goofs

When Ted calls John to convince him to come to his party, John is seen holding his phone upside down. When it cuts to him again later, he is then seen holding his phone the right way.

When Ted is escaping from Donny's house, Donny is dancing in front of the TV while sipping a soda. The camera switches to show Ted running by the door, and Donny is dancing with his hands on his hips, and there's no glass of soda to be seen.

When John is sitting on the couch and Lori is hugging him from behind, he loops his necktie twice in successive shots.

When Sam J. Jones pours shots for the guys, John's is full. When they go to drink the shots, his is almost empty.

The Jetta's hood is pushed in after it crashes into the Volvo. When the Jetta comes to a stop outside Fenway Park, the hood is fine, apart from the license plate hanging loose and some dirt on the grill.

Near the end, the characters are able to sneak into Fenway Park with little difficulty due to a garage door being partially left open. This would not be the case in real life. Also, with no baseball game going on and no cleaning crew visible, the stadium lights would not be left on.

When Robert runs to John and screams at him saying he can't have his teddy bear, John responds by punching him and knocking him out. John can get arrested and charged for punching Robert since Robert is a minor.

Near the end of the movie, the characters are able to sneak into Fenway Park with little difficulty due to a garage door being partially left open. This obviously would not be the case in real life. Also, with no baseball game going on and no cleaning crew visible, the stadium lights would not be left on for no reason.

There was no way John could had avoided serious to critical injuries when the TV fell on him. He should had suffered a broken pelvis and ribs at least.

Lori's VW rear-ended Donny's Volvo hard enough that the airbags should have deployed. However, the deployment of air bags is unreliable; sometimes they deploy at a very low speed (i.e., less than 5 mph) collision and sometimes they don't deploy at much higher speeds.

Each time Ted phones with his iPhone, he uses it against his temple when it should be against his ear. However, this obviously is played for a laugh. There is no indication that a teddy bear's ears actually work as such.

During a bath, Ted calls John with his iPhone. Before 2016, iPhones were not waterproof.

However, Ted has been seen careless with his property.

John proposes to Lori while standing. Traditionally men especially in Western cultures propose on one knee.

However, this cannot be considered a character error but just an usual way of doing things, which John masters fully.

During John and Lori's anniversary dinner at the restaurant, after John says "Let's just enjoy our anniversary dinner", the view of the street outside is waving, as if it were a printed on a canvas and made to look like the outside of the restaurant.

When Ted is taking a picture with the three girls in the park, the phone used to take the picture isn't on.

John looks over CGI Ted's eyes at several occasions, especially when talking to him while seating on the couch.

(at around 57 mins) When Sam Jones punches a hole in the wall of Ted's apartment, he incurs the wrath of Ming and initially struggles with Ming, who is attacking him with a knife (eventually disarming him). However, in a split second, Ming is bursting through Ted's door which would be impossible to do in that time frame.

After Sam Jones punches Ted's wall, before Ted's Cantonese neighbor Ming confronts him, his hands show no sign of injury.

On Christmas day 1985, a boy opens a Nintendo Action Set that was released in 1988.

The "Action News Georgia" backdrop shows damage to the Westin Peachtree Plaza. The scene is set in 1985, and the damage is from a tornado that hit downtown Atlanta in 2008.

When Donny and Robert kidnap Ted, he escapes into the bathroom to call John for help. He calls from a land-line phone. Donny ends the call by disconnecting the telephone wire from the wall, yet there is a dial tone. A land-line phone would go completely silent once its cord became disconnected.

When the band is playing at the party, the trumpet player doesn't match the song playing.

In the first shot of Lori's apartment in the beginning, the crew across the street is reflected in the first-floor window.

The supermarket where Ted works is supposed to be in Boston, but the reusable tote bags for sale at the register are from Best Yet Market, which is only in the New York City area. It's also different from the store on the cashiers' name tags.

During the car chase, they drive through the Ted Williams Tunnel and arrive at Fenway Park soon after. To do that, they would have had to drive back through the tunnel.

When John and Lori arrive at Donny's house in Chelsea to rescue Ted, they drive the wrong way on Chestnut Street (a one-way street). Donny leaves, with Lori and John following, going the wrong way on Pine St. (also a one-way street).

Lori manages to find John at Ted's home warming party, but John didn't tell her the address. Ted finds the hotel John was staying at after Lori dumped him, even though John didn't tell him where he was.

Ted is a living teddy bear, unlike any other in the world. While the film proposes that eventually his novelty wore off and that he ran through the money he made at the height of his fame, it never explains how or why there wouldn't have been endless interest in Ted and thus an endless source of income for him. In fact, the film goes out of its way to demonstrate that Ted is still quite well- known throughout the film and yet for some reason he still needs to get a job and earn a living.

John and Ted cause hundreds of dollars in damage to the hotel room when they were fighting, and the two somehow don't face charges for vandalism.

When John answer's Ted's call while riding in the car with Lori, John holds his iPhone upside-down (as evidenced by the lock button and headphone jack) for nearly the entire conversation.

(at around 30 mins) In the director/co-writer commentary, when Ted goes to a job interview at Bay Colony, the actor who plays store manager Frank Stevens is mistakenly called "Bill Kirchenbauer" when the actor is actually Bill Smitrovich.

The driver should naturally have slowed down her vehicle once Ted landed on the hood.

John's hair length changes throughout the movie.

(at around 1h 25 mins) A car drives left to right at an intersection. A sign that says "Left Turn Only", which suggests it is a one-way street going to the left.
