The doctor is in

One of my best friends asked if he could have a cameo in the Western I'm writing... how could I resist ? :-) 
A gambler and dentist with specialty in orthodontics, Doctor Urlaub can usually be found on the large gambling river boats. Though modest with his bets he has been known to throw in his supply of silver and gold tooth fillings as collateral when his cash flow is low. A man of small physical stature but extremely large on charm, he is extremely well-spoken and renowned for his superbly groomed and luxuriant beard.
