For the most part, this Super Bowl XLIII party weekend seemed relatively tame compared to previous years. That is until somebody at the ESPN party peed on Patriots' quarterback Matt Cassel.

Yes, according to the NYDN's Gatecrasher (and other party attendees) Cassel was waiting in line for the bathroom at the party when he was confronted with this uncomfortable situation:

The football star was in line for the bathroom at ESPN's Tampa Bay Super Bowl bash Friday night when a drunken reveler tried to cut in front of him. "Matt told him to wait his turn and headed into the urinals," a spy tells us. Moments later, the fella barged in and proceeded to purposefully pee directly on Cassel's leg. After security tossed the drunk, Cassel headed back out into the crowd, wet pants and all.

The identity of the wayward urinator hasn't been revealed, but hopefully it wasn't anyone from the NFL Live crew or a distraught Matthew Berry (whose prodigious imbibing is legendary at these things), that did the spraying. Good on Cassel to persevere through the rest of the evening with the wet pants, though. That's the type of intangible leadership quality that the Patriots are looking for in life after Tom Brady.
