So basically just tell some stories about how you got some unique scars (some pics would be interesting too), I'll start

About 4 or 5 years ago me and a bunch of my friends were at the beach and we were having a bon fire. We had cut down a big tree and we stood it up in the sand and we were going to burn it like that. Another thing is we had made some stuff that my friend found off the internet, you take some styrofoam and you put it in gasoline and it melts together and makes this substances that's like molassas, anyway it burn's really hot (it can melt glass bottles) and it burns really long. So we had this stuff all over the tree and lit it on fire, but there was this one spot under the tree that wasn't lit so I stuck my arm under the tree (very intelligent) while everything was burning so I can light more of the tree and then all of a sudden some of that gas/styrofoam stuff dripped on my arm while it was burning and it maybe touched my arm for less then a second and I threw my arm into the sand then the water.

So I ended up getting a second degree burn on my arm about the size of a toonie (big canadian coin), and to this day it's still there.

I was about 3, and was playing in my nans lounge just before she went on holiday. She had suitcases all around the lounge, and i tripped on one and fell face first into a glass cabinet.

As you can imagine, it didnt go well for my face. I slashed my face open and it put glass in my eyes, which to this day cant be removed. This is why i have poor long range vision

My ex bited me and now I have a scar at a unusual place it quite sucks to explain it to new gf's.

Not sure if it's like d21lewis' thread near the time Dark Knight was showing... but here it goes anyway (a true story):

Hmmm, I remember I was playing golf with friends with some plastic golf clubs. At one time, I was a bit careless on went behind my friend... Just right when he was swinging the club, he hit me on the forehead! I didn't feel a thing at first, but when I got my hands off my forehead and saw them covered with blood, I almost passed out (I did a bit later though, when my mom was screaming, lol)!

Last thing I knew, I was getting stitches at the doctor! o_o

I have a scar on my shoulder from running into a metal bar and impaling myself.

I have a perfectly circular scar about the size of a dime on my left shoulder from where this one girl decided to turn her paintball gun to 100%, and shoot me from ~10ft. For some reason she thought it would be interesting to see what 100% power would be like. We had just chrono'd all the guns, but she had a spyder, so she could adjust it without tools.

needless to say, I bled quite a bit, and boy did it hurt.

Perfectly in the middle of my forehead in the shape of a cross. Fell off a villa porch when i was 4 or 5 while looking for a ball that fell over the railing.

i got a scar on the side of my stomache when i fell out of a moving truck i was 13 at the time

I have a little Dark grey dot on the top part of my wrist. I was quickly walking down the stairs at school and some girl accidently stabbed me with her pointy pencil >_> I was than bleeding down the hallway.

You know those toilet roll holders will the pointy corners? I cut my side deep with those when I was much younger by accident.
