It vaguely sounds familiar.. A friend once told me of how she was driving in Southern California, and some guy was riding his harley and got clipped by someone and flew off the bike. That wasn't so much the part as it was that she saw him land and basically bend his body in half and he landed folded, and was still alive for a second. she said that the blood curdling scream he had before he died was something she'd never forget. There's a lot out there I wish I had never seen. Not only because it is just horrible to see, but it numbs me.
Fuck. Because of your post, I finally decided to watch Two Girls One Cup. Impossible. I had to cover the screen. Every time I peeked, I almost threw up.
Hah! I actually tried looking for it once, and couldn't find it. I just wrote it off as a "Family Guy Myth". Now I'm glad I didn't!
