This film represents the second time Jon Lovitz is associated with the song "It's Ladies Night" from Kool and the Gang. The first time was another Adam Sandler movie, The Wedding Singer (2000). In Wedding Singer, Jon Lovitz actually sings the song himself.
When Jon Lovitz was on the celebrity edition of Who Wants to Be a Milionaire in 2000, he promoted this movie and mentioned some of the costars. Interestingly, host Regis Philbin has an uncredited cameo as himself, but never mentioned to Jon Lovitz or the audience that he's in the same movie.
During the closing credits, flashes of the character whereabouts are explained. When they explain Nicky's mom (Reese Witherspoon), a picture still of her is shown saying "Mom immediately fell in love with her new aerobics instructor... Chris Farley." Giving a tribute to Chris, who died three years before the film, in 1997. The aerobics reference is referring to his classic skit on SNL that will always be hilariously remembered. Adam, and the rest of the SNL gang, were great friends with Farley.
