re: Thread Spinoff - What are the best Rivalry pranks your school has pulled off?

My Senior year before the '92 game with Texas some Aggies broke into DKR and sawed the horns off the longhorn in the turf on the 50. My corps outfit actually had a tradition of running the gameball from Bonfire all the way to DKR to deliver the gameball so when we got there we actually saw it. They had done a quick fix but you could see how the horns were about a half inch higher than the rest of the turf.
