Over X-mas vacation, I went to some stupid thing at my high school where they have college students tell the high schoolers how much college sucks. When I tested the sound system, I did it ala B&B: Testes, Testes... One, two, three?!? That was pretty cool.
There was also that time at the huge Harney carnival that I did the old guy in "The Butthead Experience." The band was taking requests, so I yelled "Play some Skynyrd, man!" Then they did.
