Continuity: In the scene where Adam Sandler is outside on the phone with his lawyer and the NYC is in the background, the boat wake disappears and reappears in the shadow of the bridge.

Revealing: When David's car does the little jump while driving to the Yankee's game, you can see that it is a stunt driver driving, not Adam Sandler. This is most obvious when the light hits his face for a second.

Factual error: When Dave is on the plane the flight attendant is talking about "how their country is going through a very difficult time right now" meaning the 9/11 attacks but later on in the movie when Buddy is in the shower and Dave is talking to his lawyer on the phone on the roof in the background you can see the twin towers.

Continuity: When Dave boards the plane the way his lapel is crumpled under the strap of his bag changes several times from shot to shot.

Continuity: After his first court case Dave goes to the Community Center where Buddy does anger treatment. When he picks up one of Buddy's books from a table there are some wooden chairs scattered in the background. In the next shot we see him from an upstairs landing, and there is now one wooden chair with its back directly at the table, and one white plastic chair where the wooden chairs were before.

Continuity: When Dave approaches Buddy in the Community Center there's a white painted brick wall in the background. When the camera angle changes the wall is covered with a colorful carpet.

Continuity: After the first court case Dave walks upstairs to meet Buddy. When he comes through the door he is holding his verdict papers in his hand, which he didn't have with him when he was downstairs.

Continuity: When Dave and Linda talk at Dave's apartment about Andrew's 'thing' Linda puts her bag on the kitchen table. When she puts her jacket on top the bag is turned by 90 degrees.

Continuity: When Dave and Buddy sing "I am pretty" on the bridge the window is visibly closed, only during their arguments with the drivers who go by (especially the taxi guy) the window is open.

Continuity: When Dave drives up the parking garage of the Yankee stadium we see him coming up the ramp to the upper level. Then the camera cuts to the side and he is seen passing by a row of parked cars which weren't there before, then it cuts back to his car still on the same ramp.

Continuity: When Robert Merrill walks up to the microphone in the Yankee stadium it's fixed on a black stand. When Dave spots it we see a close-up where it's fixed on a silver stand. Later, when he snatches it away from Merrill it's on a black stand again.

Plot hole: Just how can you get a famous author, a judge, and a flight attendant set-up Adam Sandler in such a scheme? A judge cannot use a courtroom (along with bailiffs during regular business hours) to pull off such a scam. Moreover, when he was arrested for the fight in the bar, there is no guarantee he would have been brought up before the same judge. Also when explaining to his boss about not getting a second flight in the beginning, Adam Sandler says that the plane had been turned around because of his behaviour. Show me an airline that's willing to do that for a scam.

Factual error: When Dave and Buddy get to Boston, Dave is using his cell phone, mentioning that they didn't have to take a five-hour trip to Boston just to find out that Buddy's mom was getting a Jelly Bean removed from her nose. Problem is, he's calling from the ramp staircase of Alfred Lerner Hall at Columbia University, which is in New York City, not Boston.

Other: In the scene after Dave throws a calculator at a colleague there is a very weird 3-second establishing shot of his apartment building. In this short span shadows fall over the building twice, and it changes between fully lit and fully in the dark twice. In the end there is the silhouette of some equipment covering the lower third of the screen.

Continuity: When Chuck is assigned as Dave's anger ally he puts his hand on Dave's shoulder from the side. When the camera shows them from behind his hand is on the back of Dave's shoulder.

Continuity: When Buddy stays over night at Dave's place the first time Dave ends up sleeping on the floor with his teddy in his arm. When Buddy wakes him up and takes a picture the right arm of the teddy points into different directions from shot to shot.

Factual error: Near the end of the movie Dave is trying to get to the Yankee game before Buddy proposes to Linda. One of the shots before the game is of the grounds crew doing the YMCA. The grounds crew does the YMCA in the 7th inning.

Continuity: The cabin of the airplane is that of a 767. The shot of a flying plane that comes between pre and post take-off scenes is of a 737.

Factual error: Adam Sandler's apartment is near the Brooklyn Bridge. His office is in downtown Manhattan since you can see Brooklyn Heights and the Brooklyn Queens Expressway from his boss's office. Jack Nicholson pulls the emergency brakes on the Queensboro bridge when they are heading to Sandler's office. You wouldn't take the Queensboro bridge to go from Brooklyn to downtown Manhattan.

Continuity: When Dave throws the bully-turned-monk Arnie Shankman down, Arnie's head lands on the gravel and his robe under his body. Before Arnie gets up there's a close-up of his head with his robe partly under his head.
