Weirdest video found on YouTube?

[190190tnt]

Not sure if I'm posting in the right place but
DS and I love finding and watching odd/weird videos on YouTube, probably because we were so bored during the lockdown. This one absolutely creased me up (watch until the end...)

This is a constant in our house. Watch the Toni Basil Hey Mickey vid to see the stunning similarities

How the feck did you find these? And will my algorithm be forever tainted by these ?

The Celebration, 1998
Good movie
