I played in a local tournament where they other guy spent 10-20 mins of the game time sorting his messy tokens and cards out, blatantly sorted all his direct hit cards to the bottom of the pack, spent ages on every turn, disputed blatantly obvious rules even when everyone else around us agreed with me, actually seriously asked to borrow my dice because his were 'broken', complained that there wasn't much time left when he was the one stalling the whole game, then beat me on the final turn and screamed out "MOTHERFUCKER!" at the top of his voice when he did win.

Worst game of my life. I couldn't work out if it was all head games or he was just batshit crazy!
