I have a couple. I once cut my hand open on a tin of soup and needed stitches. I also dropped superglue on myself and it burned through my clothes and left a scar on my leg. Also when I was in Iceland recently, I slipped on the ice, didn't put my hands out, and smashed my face up. I looked like I'd been beaten up, it wasn't a pretty sight. I guess you could say I'm quite clumsy. :')
toss up between two - either when broke my toe stubbing it on corner of bath last year, or a really bad sprain falling off step during step aerobics in pe at high school
