Paul Reubens, the actor and comedian best known as Pee-wee Herman, has been cast as Oswald Cobblepot's father in the second season of "Gotham."

Robin Lord Taylor, who plays The Penguin on the Fox drama, made the announcement this afternoon at New York Comic Con.

"Pee-wee Herman is playing my dad! What the hell? Oh, my God!" he exclaimed during the super-size "Warner Bros. Television Takeover" panel.

It's a return to familiar territory for Reubens, who played The Penguin's father in Tim Burton's 1992 film "Batman Returns."

"Gotham" airs Mondays at 8 p.m. ET/PT on Fox.
