TV version adds a scene that occurs right before Dave and Stoney find Link in his pool. It's a conversation between Dave and his mother about her plans of opening up a "Homeless Home" in their house and using Dave's room as a place for them to stay.
The US Region 1 DVD has several small edits made to the film. These edits seem to have no purpose at all, as they were not for offensive language or violence.
The network TV Edition of the film also features a scene in which Dave's parents are walking and talking to him on the way back to the car after they bailed him out of jail.
