When I was 14, we threw a house party at my homies house and we hired a local thug to be the doorman (actually it was the side gate of the house).
He showed up limping. I didn't know he had a prosthetic leg. I also didn't know he had a sawed off pistol grip shotty hidden in his prosthetic leg until he pulled it out to ward off some unruly thugs from rival gangs.
It was scary/funny to see this guy rip off his leg, pull a gun from it and throw his prosthetic into the bushes.
Yay for growing up in the hood.
