There is a dedication in the closing credits to set designer Sydney J. Bartholomew Jr.: "He was a crazy bastard, and we loved him."
There is a blooper scene after the credits: Stephen Merchant (Gary) films the burying scene, and the "corpse" sits up and scares him.
There is a scene at the end of the closing credits: the cops discover Fred moaning in his car again, but discover Grace is giving him a faux-job.
During the credits an out take is shown of Gary's imagining of night gone wrong
In addition to borrowing sound cues from Law & Order (1990), the end credits before they begin to scroll are in the same font and are presented the same as those in the TV series.
