In a interview on the DVD, director Tobe Hooper said that the mask worn by one of the creatures in The Funhouse (1981) was a Frankenstein mask. Hooper said that this was selected because the Universal Studios owned the image copyright for it from their Frankenstein (1931) horror film classic.
Some of the props in Joey's bedroom were owned by Shari Lewis of "Lamb Chop" fame (such as the winking ventriloquist dummy) and were obtainable because co-executive producer Mace Neufeld was a friend of hers.

Amy and Buzz leave her house in a 1966 Pontiac LeMans (obvious because of the grill and chrome badging behind headlight). The deep recess in the top of the c-pillar indicates that it is a convertible. Moments later when they are going down the road and even more clearly in the carnival parking lot when they are parking, it is a 1967 Pontiac GTO with a black vinyl top (notice the different grill insert and blinkers, as well as missing chrome badges on fender).
