Kermit the Frog visits 'Express Written Consent'

Muppet, televison icon serves up laughs while taking in Mets game

While his exact birthdate is not known -- or, at least, it's not been made public -- it's widely understood that Kermit the Frog has been around since 1955.

That would make him 59 this year, but to look at him, it's hard to believe. Even by Hollywood standards, Kermit has defied nature. He still carries that youthful look, and even close up, you'll find nary a line on his face.

Sure, history suggests that frogs do age better than other carnivorous groups of short-bodied, tailless amphibians. But still. The years have been very, very good to Kermit, who attempted to explain all of this to MLB.com host Jeremy Brisiel during a special episode of "Express Written Consent," recorded at New York's Citi Field.

"I try to live healthy and eat healthy," Kermit said matter-of-factly. "Lots of greens. Mostly mosquitoes, the green ones."

He also is an avid runner.

"I run every day, usually while being chased by a pig," he offered.

Kermit and his Muppet friends are in the midst of an intense media tour touting their latest comedy caper film, "Muppets Most Wanted." This is the eighth film for the legendary group, which finds itself this time unwittingly involved in an international crime caper while on tour in Europe.

Each Muppet film serves as a reunion of sorts, where some of the most recognizable furry faces in Muppet history reconvene for yet another crazy adventure. It's surely no simple task to find a time when all of the Muppets are available to shoot another film -- and goodness knows it can get dicey for the production company to have to work with high-maintenance agents and P.R. reps who have their own contract demands and special requests -- but somehow, some way, the plan always comes together in the end.

Credit the leadership of elder statesman Kermit the Frog, who sees the Muppets not just as colleagues. They're also family.

"It's always wonderful when the team gets together," he said. "We do consider ourselves a team. We are like a baseball team, sort of at Spring Training. We work on fundamentals, spit takes, pratfalls, pie throwers, slow burns. I guess comedy is a little like baseball, only funnier."

The conversation between Kermit and J.B. was, not surprisingly, light and breezy. But it had its more serious moments, too. Some questions aren't easy, but they need to be asked.

After all, the road hasn't always been a smooth one for Kermit. He's had his share of challenges, first having to deal with the constant pummelings he endures from his long-time love, Miss Piggy, all the while trying to overcome stereotypes that have perhaps prevented him from getting the coveted roles that typically go to taller, more broad-shouldered actors.

"As an Amphibian-American in Hollywood," J.B. began, "Has it been tough? Have you been typecast a lot?"

Kermit, ever the diplomat, answered as best as he could, without throwing anyone under the proverbial bus.

"I do get typecast," he acknowledged. "But, as far as short, green, leading men go, all of those roles go to either me, or Yoda. We split the work."

Kermit cemented his place in history as the most successful frog in cinematic history long ago, but, amazingly, he's always remained seemingly unaffected by fame and riches. And he's willing to help the next generation of frogs as they attempt to break away from the comfort of their ponds, lakes and marshes to venture into the uncertain world of show biz.

"Any advice for the tadpoles out there?" J.B. asked.

"Let your legs grow in," Kermit said, "And just follow your dreams."
