Crew or equipment visible: When 'Miranda Pandas' slide into the trash cans in front of Jack's house, you see the camera mans reflection in the car door.
Continuity: When Jack decides to take a power saw and make their car into a "convertible", Pilot is seen asleep in the driver's seat on interior shots, but the car is empty in several of the exterior shots.
Anachronisms: A URL is painted on the side of a parked trailer. It's partially blanked out in one shot but visible from another camera angle. No company would have been advertising a web site in 1994.
