During the scene when the three boys are introduced to their new D.O.G. dorm room, Robert/Roberta opens the closet. A string of purple beads is hooked onto the red purse hanging off the door. In the very next scene when Robert/Roberta grabs the purse the string of purple beads is not there anymore.
During the first scene with Adina and Jimmy, Jimmy runs up and slams the door. Adina does a double take. When he turns back to Jimmy, his left earring falls off and down the front of his shirt. When Jimmy starts taking off his robe you see Adina's face and the earring is back on his ear.
During the scene when Dave/Daisy and Adam/Adina are hugging in the room during the K.O.K.-tail cruise, Dave's/Daisy's purse is in his left hand. In the very next scene, when Leah walks in on them, you can clearly see that Dave's/Daisy's purse in hanging off his right arm.
During the hallway scene with Jimmy and Adam/Adina, a blonde girl in a green shirt is walking just behind the two. When the scene changes to Jimmy slipping the piece of paper into Adam/Adina's shirt, you see the blonde in the green shirt further back walking towards the two.
During the DOG/Tri Pi. Football game, the scene opens with the girls getting ready to play, they show the Tri pis warming up during a foggy morning, the dogs warm up in the sunshine and the referee calls the teams during the late afternoon.
When the boys join the D.O.G house, you see everyone in a circle with food in the middle. When they go around and introduce themselves and it comes to Patty's turn, she says "I'm a very gentle person" and puts a mug to her mouth, accidentally breaking it. Nothing comes out of the mug, and if she went to drink something, wouldn't it all spill out when she broke the mug?
When Adam tries to seduce Jimmy in his room and begins screaming for Dave's help, the shot is from outside looking in through a seemingly broken window. However, when we see the inside of the room, the windows are intact. They're only broken after Jimmy is thrown out of them, not before.
