well. . .
This one time (when i was 7) i stubbed my toe on the curb of my street, and ripped off my big toenai; that hurt a lot.
and this other time i decided to go skiing on a run that had no snow on it, (launched a cattrack, 30ft. only to realize in the air that this was not the same run i had jumped onto last lift ride) broke my nose by smashing into my own ski pole, and shattered my knee-cap into 6 peices, funnest ambulance ride of my life apparently i was makin wise cracks the whole time i was on morphine, then it just knocks me out. all in all i end up with 25 staples in my leg and two permanent screws.
summary: shattered knee cap (6 pieces) + broken nose = a shit ton o pain
