Ned's auto shop and gas station is the same set used in the TV Show "Roseanne", where it was the setting of Dan Conner's motorcycle shop, Lanford Custom Cycle.
A gag on episode #6.9, "The Tool Man Delivers", featured Tim striking a match at a gas station and blowing up. The footage of the body on fire and the explosion was originally shot and featured in the film Darkman (1990)
