Revealing mistake: In the scene where Harry and Lloyd first meet by running into each other, when it shows it in slow motion, you can see Lloyd brace for an impact when he's not suppose to know Harry is coming.

Store Clerk: Enough! You're it! And no touch backs, no do overs, no erasies, and this whole store is home free!
Harry: Lloyd, can he do that?
Lloyd: Oh yeah Harry. He can. He did. And now...it's on like Donkey Kong. Pay the man.
Harry: Pay the man.
Trivia: The guy who plays Lewis in the film also plays a guy called Lewis on the TV sitcom Even Stevens.
Question: As Lloyd and Harry follow Jessica and Principal Collins with a shopping cart, what explodes at the Big A convenience store? (01:06:00)
Answer: Because Harry and Lloyd had poured gasoline all over the car as well as let the pump keep running when they left. So when the hot ash of the store clerk's cigarette hit the gas fumes, it caused the explosion.
