In the baseball scene, Rudolph Giuliani yells "You can do it." which is a regular line in Adam Sandler films. Rob Schneider says it in "The Waterboy", and then again in "Little Nicky". Sandler himself says the line in Schneider's "The Animal".

When Nate is losing his temper in the first fury-fighters meeting, his voice was not clear so what you hear on the DVD is not his voice, but Adam Sandler's voice that has been dubbed over.

In the scene where Buddy is talking about how he has fallen for Linda, Adam Sandler wears a shirt that says something like "CENTRAL PRIDE." Adam Sandler went to Central High School in Manchester, NH and this is a tribute.

Meatball the husky cat isn't really husky; he was just wearing a fat suit. The filming crew had to keep fans constantly blowing so he didn't get too hot.
