I used to do a lot of sketching and drawing a million years ago. When I was 15, I drew a picture of one of the guys from Sha Na Na (Donnie) and took it with me when my friends and I went to their concert. We were sitting quite a few rows back, but we passed the picture forward and it managed to get to Donnie on the stage. He held it up next to his face and showed everyone in the audience. Never saw it again after that (I think he kept it up on the stage someplace).
Anyway, my friends and I screamed like a bunch of teenage girls. (Oh wait, we were teenage girls).
