My urologist was a big fan of Password, but of the (later) Bert Convy and Gene Wood years (Super Password). In fact, he’s got a sign (almost like a poster) of Gene and Bert hung up in his office. Under their heads is the caption “The Password is ‘Scrotum.’”
OK, I just made that up, but it would be kinda funny.
I had a proctologist once who was a huge Paul Lynde fan ("Let's see the center square..."), butt I stopped going.
