I've got one, which has been posted on other boards before, from my junior year at OU.
Back in the peach-basket days of the 1978-79 season, OU hosted Cal-Bakersfield in a game right after finals. It wound up a blowout, as the eventual Big 8 champs rolled visitors by about 25-30 points.
The interesting part came from the students' reaction to one of the Bakersfield players. He was a balding, "every-man" looking guy named Ethan Aronie. The thing that caught the students' attention was that he had just "E" on the back of his warm-up top. And, this was back when Elvin Hayes of the Washington Bullets was still in his prime, and his signature move was a turn-around jumper, after backing down his defender, while the home crowd chanted "E-E-E-E-E-E!" the whole time.
Since the game was in hand, the students started rooting for the chance to do their own "E-E-E-E-E-E!" chant. Aronie received a few of those but passed off without shooting. Finally he made a move on Al Beal and got fouled with about three minutes to go in the game, all the while being serenaded with "E-E-E-E-E-E!"
Aronie went to the line and clanked his first foul shot. You'd have thought the home team was about to lose, by the crowd reaction. But he made his second FT, and the place went nuts. Then, not long after, he was taken out of the game, and his replacement was verbally pummeled with boos.
And, with about a minute to play, the students started chanting, "We want 'E!' We want 'E!'" He never got back into the game, and I've always wondered what he thought of that attention.
On a funnier note, my brother tells of his med-school days, when Sam Hill of Iowa State would visit the LNC every year. One time, during the introductions, Hill trotted out when he name was called, probably NOT knowing that a guy in the "BLOB" section was up there with a newspaper behind his head, flapping them like Dumbo ears (and even rolling his head like Dumbo the Elephant). My brother said the guy doing the Dumbo thing had a facial expression (of dead-seriousness) that was about as funny as the act itself.
