Roadies lightbulb joke

Question: How many roadies does it take to change a lightbulb?
Answer: One, two! One, two! One, two!
Answer: None. "I don't do lights. That's the light crew's job."
Answer: One: Upon finding no replacement, he takes the original apart, repairs it with a chewing gum wrapper and duct tape, changes the screw mount to bayonet mount, finds an appropriate patch cable, and re-installs the bulb fifty feet from where it should have been, to the satisfaction of the rest of the band.
