My worst (and funniest) was my high school band. I got suspended from school after a talent show that had went horribly wrong for me... I don't know why they had a problem with the performance....something about kneeling on the judge's table in front of the pretty teacher with my guitar between my legs giving the strings the "stroke"... maybe it could have been my facial expression that got me in trouble for that one, but hey! I saw Steve Vai do it on MTV, so I blamed MTV for it....

I didn't care though, I got one hell of a standing ovation for having the "testicular fortitude" to do it in the first place....
