What's the most embarrassing thing you've ever done?

[SERIOUSLY THOUGH]

I was a competitive swimmer back in the 90s in my region - During this competition, I was in the freestyle final (freestyle being using whatever stroke you want, not hip-hoping krumping across the pool) and did the world's most kick-ass powerdive when the race started.

Unfortunately the force of entry kinda pulled off my swimming trunks. But I thought "fuck this" and like a boss did my whole race in my birthday suit. I came second
