'best story ever' - I don't see your point here. People say Schindlers List is one of the best films they've seen, does that make them Nazis, revelling in the fact Jews were slaughtered?
Bloody hell, people have even made GAMES where you urinate on people for a bit of a laugh. It's a funny thing.
It's not funny to do it do someone dying or obviously in need of help, which is why that guy is a **** of the highest order, but things like that are amusing when viewed in their own light. Would you be laughing (or even just less disgusted) if I had urinated on Sic after he and I got wasted and he fell into a doorway?
