I had to use once my Kramer Duke (Headless bass, Steinberger XL lookalike, normal small tuners on the body's low end instead of double ball system) as a spear to poke and get rid of a drunken fellow trying to get to sing right on the lead singer's headset microphone (almost kissing her), all the way while I was also playing and singing backing vocals, at the same time blocking access to my microphone with my right ankle to prevent another drunk guy from singing through it, and with my right leg over the monitor (Iron Maiden's Steve Harris-like) to block another guy from passing under my microphone's boom stand to also reach the singer. It ended in some sort of dance that I'd only wish somebody had recorded...
