Last month on an Orlando radio show, Geraldo Rivera repeatedly criticized Keith Olbermann, calling him a "punk" and a "slimeball" (among other things).

Then, with the prodding of the radio hosts, he went a step further, Scott Maxwell blogs. "He called Olbermann a coward -- specifically a '[female part of the anatomy] who wouldn't walk across the street against the red light.' He then said he was ready to fight him, saying: 'I would make a pizza out of him.'"

"This is hilarious," Olbermann responds in an e-mail to TVNewser. "I'm nearly 6'4", Geraldo more than a half a foot shorter."

He added: "It was a long time ago, but I remember when I was a kid, he was a pretty big deal, wasn't he?"
