Strange Question/Locating An Episode
Been years since I've seen it. Not sure if it's UCB, Mr. Show, or another show, altogether.
It's a sketch set in a living room, possibly for an intervention, where the guests, or a guest, is addicted to sticking random objects up their arse.
Indication of said item involves the person putting a sticker on it, designating that it's theirs.
I can only imagine the responses I'm about to get, but this is a legitimate sketch from a sketch comedy show airing in the late 90's.
