Absolutely batshit viral video from before Youtube in the early 2000s. Its incredibly dissonant to listen to, so I figured I'd only watch for a few minutes but I watched the entire thing and then started from the beginning. Amazing how nonchalant and chill all the people are. The sound design goes from grating to hilarious the longer you watch it.
