Here ya go!
LEEROOOOOOOOYY JEEEEENKINS!!!!!!!!!!! Is it just a coincidence that my name is Charles Jenkins?
I would have to say Chuck Norris.
Well Leroy Jenkins ran into a WoW dungeon unprepared shouting his name (which is what he is famous for) and got killed instantly and got the rest of his group killed quickly too XD so yeah Chuck Norris will win
