Matt Cassel might be a Patriot (at least until they trade him), but he apparently wasn’t ready to break out his bayonet for a swordfight at a Super Bowl party. According to the NEW YORK DAILY NEWS (who apparently had sources deep inside the restrooms at all parties), one drunken fan decided to “write his name in the snow” - but substituting the back of Cassel’s leg for snow.
I can guarantee you that this sort of thing doesn’t happen to Tom Brady. In fact, Brady probably hasn’t had to use a public bathroom with the unwashed masses since his rookie year. (As with all famous people, he has access to special, secret restrooms at all stadiums, complete with golden bidets, seat warmers on the toilets and free caviar at the wash stations instead of sticks of Extra gum.)
