That guy's pathetic, he's using a condition to mask his inability to behave normally in society. The link below is of real Tourettes sufferers, it's a bit disturbing but I have to admit, it makes me laugh....
Worked with a guy with touretts he didn't have it that bad though. He would constantly crack his head back though and I mean hard. Im amazed he hasn't broken his neck. He acts like an idiot all the time that problalby has to do with it too..
