This weird, warped overdub of Sesame Street is one of many on a mysterious videotape entitled Sickcomp, dating from around 1995. The majority of information I've gathered about this is anecdotal, since little can be found about it online aside from a few YouTube comments and a conversation I had with a user on here who had the tape around this time(shoutout to u/sleepyeyed, you rock!). From what I've gathered and seen, Sickcomp was essentially a compilation of short, shocking and bizarre videos, including outtakes from commercials and TV shows, obscene and offensive overdubs of Davey and Goliath and Sesame Street, footage of the Budd Dwyer suicide and a man being run over repeatedly on a race track. Some of these can still actually be found on YouTube.
I've been fascinated with this since I first stumbled across the Davey and Goliath overdubs, which have now been deleted from YouTube altogether (to the best of my knowledge). The whole tape, or what can be found of it, has the weirdest feeling to it.
Shades of the Max Headroom signal hijacking, no?
