Director Peter Berg provided Walken with a copy of the movie, and after watching it, Walken decided to use the phrase.

According to Seann William Scott the "thunder and lightning" bit was just a joke, but was so entertaining it was kept in the film.

Hatcher's tooth-fairy speech was a substitution for him comparing the situation to Pooh stuck in the door to Rabbit's house from The Many Adventures of Winnie the Pooh (1977) after Disney threatened to sue over it.
