holy shit- that knee pic is super gnarly.
I was a bar back at a restaurant when i was a senior in high school and the stupid bartender had thrown broken glasses into the garbage (you're supposed to use a separate container). I had a giant bag of trash and it was heavy, so I knew I needed to power clean it over my shoulder in order to carry it out. I heaved it up over the front of my body and over my back shoulder and felt a scratch as it passed my leg. I walked out and threw it in the dumpster and then on the way back to the restaurant noticed a trail of bloody shoe prints. A piece of glass had gone threw the bag and as I passed my thigh it sliced through my pants and into my leg, then bled down my leg and shoe as I walked. Can't remember how many stitches--the scar is only about 4" but that shit bled like a mother bitch.
