A Perfidious Pieman is Simon

Simon the Pieman returns to steal 4 million Turkish coins ("piastres"). In the process, he kidnaps Barbara Gordon, and sets up: Batman in a belfry, hanging on to the clapper of a swinging bell to avoid ending up in the soup; Robin running to dodge candles that will light dynamite fuses on his ankles; Batgirl to be thrown down a well in a pumpkin shell; Batman & Robin trapped in a submersible pie heading to crash into a reef; and Batgirl to be crushed under a PIE-zoelectric crystal. Where does he get all those marvelous toys?

Some voices:
Batman: Olan Soulé
Robin: Casey Kasem
Batgirl: Jane Webb
Narrator & Simon: Ted Knight (2 years BEFORE "Mary Tyler Moore")

TVLand once stated that Olan Soulé voiced Batman on Radio in the 1940's, but this is in dispute. TVLand has been known to make mistakes. We do know that Filmation's voice of Superman in their 1966 cartoons, Bud Collyer, DID voice Superman on Radio in the 40's.
