why chili sauce?
You got me. Probably an inside joke.
Our lead guitarist's name is Robert (he's a Deputy D.A.), and he never goes by any nickname, but I just cracked myself up one night when we were coming up on his solo, and I yelled, "TAKE IT, BOBBY!" I was laughing so hard, the rest of the band was chuckling through the whole rest of the song. It was the first and only time any of us had ever called him anything but Robert, and it just came as a shock. He wasn't pissed or anything, but I've never done it since. It would just take the edge off that one time.
