Corrected entry: When Buddy and Dave go up to the upmost garage deck to get Buddy's car the most natural thing would have been that the elevator attendant waits for Buddy's car as this is the only way to get down. Instead he goes down. This, of course, is required for Buddy to push the car behind him down the elevator shaft. That the car lands on the ground and not on the roof of the elevator is another slip in this short sequence.
Corrected entry: In the scene where David and Galaxia are talking in the back of Buddy's Car, Galaxia says "I'm a Lady..." and then it shows David starting his recorder. Later, when he is telling his lawyer about it, he plays the "I'm a lady..." bit, but he couldn't have done that because it was before he pressed record.
Corrected entry: In the part where Dave's making Buddy's breakfast, one of the windows is cracked. When it goes to the close-ups of Buddy at the table, the window's not cracked.
Corrected entry: In the scene where Buddy and Adam Sandler are at a table in the bar, where Buddy tells him to hit on the women, in the first shot you see a women in a black dress going to the back of the bar, in the next shot you see her closer to Buddy and Adam Sandler then before the angle changes.
Corrected entry: In the scene where Dave goes and confronts his childhood bully, the bully says something similar to: "What do you have to say about my god?" A Buddhist would never call Buddha his god because they don't consider Buddha god. Buddha is simply the "enlightened one" who is close to their god. A true Buddhist monk would never make such a grave error.
Corrected entry: In Adam Sandler's apartment, there is a buzzer to get into the apartment building. This is made clear by his "anger buddy" buzzing him to come downstairs once. However, when Jack Nicholson comes in to move in with Sandler, he rings no bell. He just knocks on the door. This happens several times (people comming in with no buzzer). How do they get in?
