There was a CSI episode one time where a guy was found with letter tiles in his throat. What happened was there was a word game tournament (think Scrabble) where if you thought your opponent played an invalid word, you challenged it, otherwise you played on. One guy plays a word the other guy doesn’t recognize, the other guy raises his eyebrow and decides its not worth risking the penalty. He then plays an S to pluralize the word, gets challenged by the first guy, and loses. Later he accosts the first guy and stuffs the letter tiles down his throat and kills him.
