Liberace played a double act in

[@georgegolden5041]

I remember watching that rerun. I was impressed with his dual role. The bad brother was the tough guy, good episode

[@PaulsToolReview]

Liberace also played himself popping out of a window as Batman and Robin rope climbed one of Gotham's buildings. Other notable guests were sammy davis, Sinatra, lurch ftom Adams family, just to name a few.

Yes. They also had Werner Klemperer as Colonel Klink - quite bizarre when you think about it.

I remember those window segments. Celebs of the time kept popping. A fave of mine was the Green Hornet and Kato popping up for a crime fighters convention. A few episodes before, Batman and Robin thought they were the bad guys. and did the invite to the convention for the Cape Crusaders get lost in the mail?

My favorite was Andy Devine as Santa Claus.
