We're a bit late to this story, but it's still a goodie.

A Turkish man has entered medical history by having an unfortunate bodily response to his own praying:
The problem - involuntary jaw muscle twitching - had been croppingup for two years. It occurred only when the man recited the Arabicprayers he had been using since childhood, never at other times. Itwould cease right after he finished praying.
An extensive battery of tests showed him to be otherwise in good neurological, muscular, and dental health.
Thedoctors came up with a simple, fairly effective fix: they had the mantouch himself on the jaw. Usually, this interrupted the spooky jawgyrations.
There's even a video of the poor guy online, but you'll have to find it yourself. He has enough problems.
