I have a 5-6cm scar, groin area, but it's in the crease between thigh and groin so you can't see it unless you really look, that's from a hearnea (sp?) operation when i was 11 months old. Almost sliced half my finger off at work, holding a small rectangular blade and dropped a foam box with 20kg of rock in it and it pushed the blade through my finger. Stitches for that one haha.
Got a 5-6cm scar through my left eye, got in a massive brawl at a train station about 3 years ago, turned fairly nasty and i copped a big lump of rock (the ones they have on train tracks) thrown full force from about 2m away, that hurt.
