Charlie begins putting on his right glove while he is standing behind the bucket of chum and talking to Jake. He is then shown putting on his left glove, but his right hand has no glove on it.
The number of video games that Charlie grabs changes from 3 to 4 and back to 3 while Charlie is in the store with Jake.
Charlie reads the card that Jake made for him, then sets it down. Alan then tells him that he barely took any time to read the card.
However, Alan was facing away from Charlie while he was washing dishes, so he could not have known how much time Charlie spent reading Jake's card.
When Charlie and Alan pile out of the room with all the birds, Alan runs into the wall and the set wall moves.
Charlie tells Alan he wants to get a drywall guy to seal up the room that the seagulls are in, but the hallway walls are made of stucco.
