What's the most useless skill you're weirdly proud of

[Taker]

I can recite the alphabet backwards in under four seconds, learned it on a genuinely boring car trip about fifteen years ago and it has never once come up as useful, but I still do it occasionally just for myself

Everyone's got one of these, some skill that took real effort to build and gives you a strange little jolt of pride even though it will never help you get a job or fix anything or make you money

Mine also extends to knowing an unreasonable amount about a niche topic nobody around me cares about, doesn't matter, still feels good to have it in the back pocket somewhere
