Weird Idea #1 - The Ear Worm

From Wikipedia.
This is what we call an oorwurm (ear wurm) in Dutch.

Inspired by this video: https://www.youtube.com/watch?v=tA6GwfeDYyA

Setting: Completely normal day to day modern day average people.

Genre: Sitcom

The game night is an episode. The problem: An ear worm. There's a catchy tune that slowly worms itself (heheh) into everyone's mind. By the end of the episode everybody is humming it. Hijinks ensue with people trying to avoid it, getting rid of it finally and getting it stuck in their head again by another person. Players try to find silly, funny and somehow relatable ways to deal with it.

Some kind of resolution in the end, where they figure out it might not be so bad after all, or everyone finally got rid of it, but someone mentions that he got rid of it finally and it reminds the others, which starts it all back up.

Probably using something like Fate or even make it into a FIASCO playlet? I dunno. This is a weird brainwave. No bad ideas in brainstorming.

VARIANT: If you wanna get more fantastical it would fit in nice in early Star Trek as some kind of Psychic Ear Wurm. Perhaps a tune stuck in the head of a psionically powerful person, whose powers unwittingly broadcasts it to the other people around them. Otherwise harmless. Doesn't know they're doing it, just like people sometimes don't know they're humming a tune. Perfect for one of those weird episodes like Buffy's Musical episode. Which leads to...

VARIANT: In a fantasy setting where magic exists in some form or another, it could be a curse of some kind.

Alright I'm done. I think.
