Yes, zapped, that's the "Inflate-a-mate" sketch and it is on Volume 1. It's a great skit and the actress does an excellent job. She's gorgeous and is also in my favourite sketch; "I need a bra" .
Yes kids after almost 20 years, determination finally pays off again, although I don't own it yet, but somebody other than myself knows that it exists! I also got a copy of miss teen U.S.A 1990 in the mail this week, which I had seen only once on TV, and thought I surely would never find a copy of. For those of you lucky enough to have caught it way back when, I will give a brief reminder: at that time, Madonna's song "vogue" was popular on the airwaves. As part of one of the routines, the eliminated contestants were posed standing in the background, while the remaining 12 would walk down a set of stairs, do a few spins in front of the camera for about 20 seconds, then walk off stage as the next contestant came into view. The other girls would strike a pose and hold it, until another girl came down the stairs, then change the pose for the next contestant. I wasn't quite as inspiring as I had remembered it, and the fact that this was on VHS originally, then transferred onto DVD-the picture quality is grainy, but this and the Bizarre sketch were the last two I was looking for.
...google long enough, and ye shall find! 
I have heard of the other sketch, but I don't think it's on this vol.
