I had so much fun playing Ebenezer Scrooge.  Sam Melnikov as Tiny Tim was the perfect foil for my curmudgeonly temperament. 
People have been teasing me that a mean, miserly, bitter role was too easy. "Try reaching, Tom, try reaching for crying out loud." To them, I say, "Bah! Humbug. A bug that hums. Huuuuuuuuummmmmm! Humbug."
