How's this - I was on a gig with a big band when I was about 16, playing tunes during set-up time between acts at a talent show. We were in the middle of a nice quiet vocal, and I slid my chair just a little too far back on the riser....no chair rail, and riser about 5' tall....needless to say, the chair went crashing off the riser, I landed flat on my butt, and I had all the audience attention I could ever possibly want! I was just lucky not to smash my horn or have my skirt over my head! Since then I've been VERY careful with chairs on risers...
