Input: Text: of coarse this didn't happen today. if it did, i wouldn't be talking about it. it happened a few years ago and i remember it like it was yesterday. so, i'm 6'4", 185. not very muscular, not to thin. just an average swimmer build male. i'm a few months into sticking to a good work out program. i'm walking into the gym feeling great, earbuds in and blasting music (big mistake). i see an open treadmill right between two hot chicks and decide to impress them with my endurance (biggest mistake). i go to step up on the treadmill and the motherfucker was already on at supersonic speed!! it must have looked like something from a cartoon, i think i did a flip and it felt like i got hit by a train. earbuds yanked out, bottle of water went flying, not a pretty sight. i had just renewed my membership for a year but i was so embarrassed, i didn't go back there for months.

TIFU by not paying attention when I went to the gym.
