Character mistake: In history class, Mr. Hand tells the students that the Platt Amendment was an amendment to the U.S. Constitution passed in 1906. In fact, it was a rider attached to the Army Appropriations Act of 1901. (00:23:05)
Character mistake: Damone claims he made a $16 profit by selling the two scalped Van Halen tickets; since he sold the tickets at $20 each when they originally cost $12.50, he actually made a $15 profit.
Answer: This could be considered a mistake. Some people say the pizza cost $1.05, and he gave her $1.10, with 5 cents back. But if you watch the register, she rings up $1.10 before he hands her the money and then it shows $0.05. It seems this part wasn't in the script, so was added as filler and some of the sequence is slightly off.
