Craziest: I went with 3 friends to the '07 road game at Illinois. After an entire afternoon of drinking we ended up at the game on the border of the Michigan section in the upper deck, so we were seated next to Illinois fans.
After some friendly banter before the game it turned rather vicious when some grown Illini fans were shouting that, "Lloyd Carr deepthroats!" and proceeded to make angry gestures towards my friends and I. This only lasted so long before my roommate decided to speak up, naturally the one Illini fan threw a punch and soon enough we had ushers and security come up and question what had happened. Luckily we had enough people around us to back our story but it was the weirdest experience I've ever had at a game. Needless to say I probably won't be heading back to Champaign anytime soon.
