Borderlands 1
T.K.'s Life And Limb

I used to be a go-getter like you...till a skag named Scar bit my leg off. I stabbed him through the eye, but it didn't kill him! I had another go after Dr. Zed whipped up a replacement leg, but Scar got that one, too! Pulled the thing clean off, and I was barely able to drag myself home. Say, you mind getting my leg back from Scar? If you kill him while you're at it, I got a special gift for you!
