Do a premiere of a handyman show (with studio audience)
with a one armed man as the host with a very real and authentic looking fake arm right down to the phony blood. He accidentally cuts it off on a band saw and wraps his injury in a dirty shirt and keeps on working (this guy is REALLY dedicated to his job). He invites the studio audience up for BBQ with his mutilated arm as part of the meal. This can also work in the general public with tool demonstrations.
