For a short time I held the record for being the youngest person alive.

Me: person who knows the fewest people to have broken a world record! (0)

Do videogame records count? A friend of mine from uni holds dozens of works records for a reasonably well known indie game. She's showcased it on a Games Done Quick charity Steam, too.

I can't say the game or it'll doxx her, though. She has most of the records.

I know a guy who once held the Guinness world record for the loudest whistle. It was eventually topped — records are made to be broken — but he held the title for a couple of years.

He’s known as “Whistle Monsta” and NFL fans might know him from Saints games. He’s a long time season ticket holder and they show him on TV a lot.

I'm well connected within the sideshow and fire performance worlds, so there's a lot there. Most fireballs from a single torch for one. Definitely a few Rubik's cube related ones too.

Still me, as part of a group. Like I said in the other thread, world's largest scavenger hunt.

The bakery down the road from where I grew up used to hold the Guinness world record for the largest version of a local specialty.
