I'm pretty savvy when locating little oddities from the past but here's three that I'm afraid I may never see again.
Somewhere between '83-'86 I had my first glimpse of MTV while spending the night at my grandparents house. I remember seeing this video of a neon pinkish man with a wheel in place of legs wheeling around and singing in what appeared to be the innards of of a VCR. I was transfixed by this until my deeply religious Grandmother abruptly flipped the channel.
Next, a few years later I watched a teen summer camp type movie which I could have swore stared a young MICHAEL J. FOX (IMDb says no) but there was some subplot about a disappearing kid and a weirdo/killer in the woods named Wally. I think the kid finally turned up but Wally may have actually just been a little slow but not a maniac.
Finally, in the early '90s I was ill and my mother had taken my little brother to the video store and he picked out some bargain bin-type kids fantasy flick. The film involved a kid and a likable vagrant drifter who happened to be from, or at least aware of, some fantasy realm that looked like GYMKATA meets the 'It's a Small World' ride. Extremely bizarre.
Anyhow, if any of these happen to strike a bell that would be amazing, otherwise I may have imagined them.
