Batman and Robin “climbing” the walls of Gotham City usually resulted in a cameo appearance from some of the biggest names in entertainment.
Dick Clark, Sammy Davis Jr., Don Ho and Art Linkletter all made an appearance.
Col. Klink of Hogans Heroes warns the Dynamic Duo against letting Col. Hogan get a rope.
My personal favorite is Andy Devine as Santa Clause.
