Chris and Mikey--It's funny, as a child I conflated Rip Taylor--The Gong Show, The $1.98 Beauty Pageant--with David Wayne's effete, squirrelly portrayal of the Mad Hatter.
Wow, you just jogged a memory. I think at one time I had him pegged as the Mad Hatter too! I didn't realize the Mad Hatter was the little white-haired doctor I saw every week when my Mom watched House Calls!!!
