Character mistake: Pete says that Terry Bradshaw's corvette is a '75 stingray. It is actually a 1981 or 1982. 1975 corvettes had a rear window that was perpendicular to the ground. 1978 and newer had a sloping rear window.

Character mistake: John Lithgow is 'Doug Whitaker', however, in the scene where they invite him onstage for the improv act, they ask for John Whitaker to come on stage.

Character mistake: When Alex Vreek's father wakes him up to show him the board game, he knocks on the door and yells Tim or Jim, not Alex.
