No, sorry to break it to you but there is a basis for this 'Urban Myth'. I refereed/DMed/GMed a number of games for a part timer
who would absent mindedly suck on my d20
s. As the game progressed and the tension mounted I would watch in horrified facination as the frequency of the sucking action increased until the inevitable moment of:
"Erruuup! Oh sorry mate, that was your dice right?"
This occured on many occasions. It may sound too strange to be true, but anything can happen in a gaming session, and it usually does.
