My freshman roommate was a card, and he got onto Morton Downey Jr. and launched into an impromptu rant about nothing in particular, just playing the typical audience member. Hilarious.
He was always doing that, first week of classes, they had a Friday night movie night and the movie was Beaches. There were two showings and we went to the second. Every time we passed a girl leaving the theater who was crying he yelled out 'Loopy Broads!!'
