The other day I rewatched that Judgment Day match between Eddie Guerrero and JBL. Anyway, it wasn't a really bloody match until JBL landed a chair shot on Eddie's skull and cracked him wide open. There was so much blood. The fact Eddie could still wrestler for a good twenty minutes despite blood dripping from his head is amazing.
That was brutal as fuck.
I also loved Edge vs. Mick Foley at WM 22 with the burning table. Awesome, awesome match that one.
What are some of your favourite bloody/hardcore/brutal matches in wrestling?
