Details magazine's Jeff Gordinier once drove with Daniel Browning Smith, aka Rubberboy, to a restaurant for some tacos. "While we sat at the table," Gordinier later reported, "he removed his left arm from its shoulder socket and began to spin it around on its axis. The top bone of his arm popped out of the shoulder, turned 360 degrees like a kebab on a spit, then locked back in. His armpit was upside-down. He did this as casually as you might scratch behind your ears."
