During the parade when Chuck and Larry are quizzing each other on different aspects of each other's personalities, Adam Sandler and Kevin James each give their real birthdays when asked.
The book that Chuck (Adam Sandler) reads the kids as a bedtime story is "The Puppy Who Lost His Way", the same book Billy's 1st Grade teacher reads at story time in Billy Madison (1995).
Release prints were delivered to theaters with the fake title "Apple Bottom".
It represents Adam Sandler and Universal's fourth collaboration and their first movie together in eleven years. It is also Sandler's first major film not released by Columbia Pictures since Little Nicky (2000), which was released by New Line Cinema.
The fire companies portrayed in the movie are Engine 506/Ladder 223. In reality, FDNY engines numbered in the 500's are used as spares or are fully equipped on reserve status. Ladder 223 is also another fictional fire company. For the film, the firehouse used was FDNY's Engine 280/Ladder132-built in 1912 and located in Prospect Heights, Brooklyn. The patches and motto used in the movie are the same patches and motto for the real fire companies assigned to the firehouse.
