P is for the Penguin
Was there any other Penguin? I know I'm not the only one who read the comics in Meredith's voice? And let's be real the 1960's Batman is the only Batman worth watching.
Did you know, that Meredith developed his grunting "Penguin" laugh out of necessity. Meredith had given up smoking some twenty-odd years earlier, but his character was required to smoke with a cigarette holder. The smoke would get caught in his throat and he would start coughing. Rather than constantly ruin takes in this matter, he developed the laugh to cover it up. "Actually, it was a pretty funny noise for a penguin to make," said Meredith. "I sounded more like a duck." Needless to say, Meredith gave up smoking again immediately after the series ended.
