Me and my brother were in a bar one night watching a game and these asshole cowboy fans were next to us.. As the night wore on they became more obnoxious.. Well it was there turn at the pool table and while they were playing my brother grabbed there pitcher of beer that they left on the bar and proceeded to lower it below the bar and piss right in it.. I almost couldnt contain myself when they came back and poured each other another round.. The look on there faces when they took a drink was memorable..they ended up drinking the rest of the pitcher.. To this day I never leave my drink unattended......
