I got a great letter this week from a fan named Harold Dickinson.

He writes, "I'm trying to get the name of a cartoon from the late 50's or early 60's. It had two characters who -- at least in my memory -- remind me of Penn and Teller. The one character was tall and bombastic, the other was shorter and never spoke- although he would whisper to the other character. I believe the smaller character was named Leonardo- but I wouldn't swear to it."
