You often see them in tourist spots.  I've seen them along Fishermen's Wharf in San Francisco, along Bourbon Street in New Orleans and along International Drive in Orlando -- it's those statue street performers.  Some of them are amazing.  No matter what you try to do to get a reaction from them, it's just like looking at a statue.

One performer in Australia took as much abuse as he could take from one drunk guy, and I think you'll agree the drunk got what he deserved. But it's amazing that the performer went right back into character, almost as if nothing happened.
