The song "Here I Go Again" by Whitesnake is played four times in the movie - twice with the words, once without, and once hummed. The band Whitesnake is also mentioned by Mitch when he references Nicole's high school jean-jacket. Frank also wears a Whitesnake t-shirt at the very end of the movie, during the credits.
There were plans to produce a sequel, with the main characters on college spring break. Upon reading the script, Will Ferrell when promoting Semi-Pro (2008), said that he and Vince Vaughn had the same reaction when the story just felt like it was repeating itself.
