take your pick:
fell off a raleigh extreme aged about 8ish and hit a wall. a reinforcing wire went through my helmet at the back, i have a lump like a little spot there where it went in the flesh (but not my skull, tuff top saved my life) - cuts and bruises, and a bit of a nasty tear on the nose. all faded away now.
Sliced my wrist aged 16 on the ragged bootlid of a 1983 honda civc, got a 3" deep wide scar running up the main vein. That went a gusher.. i was like *looks at it* "cool...oh ****" ran and got help
Had a nearside rear blowout at..er.. speed.. in a modded S13 Nissan 200 "Silvia" a few years ago. Lucky it had a FIA crash structure(i like my safety stuff), it spun a lot, hit a kerb, went over a few times, hit a wall, spun a lot, and came to a rest against a steel lamppost
Bruises and strains. That's it. the car was, to say the least, totalled. I was v.lucky to get out of it.
Don't drive quite so quickly now either.
The one that hurt the most i got to say was when i jumped off some stairs, like, the last four, and landed with one foot on some uneven floor and went over on my ankle. i was
heavy at the time, like, 17 stone. That really, really hurt. Couldnt walk for a few days, it was painful for a couple of weeks, but it wasnt damaged beyond strained muscles. Boy it hurt though
EDIT: i have a little barely visible scar on my left index finger from where a parrot bit me
