Gene Simmons stopped by 'Late Night With Jimmy Fallon' (weeknights, 12:37AM ET on NBC), and we learned way more about his freakishly long tongue than we really need to know.

For example, it took him a while to figure out what to do with it. Also, it gets musty in there, so he has to air it out. Did we really need to see it, though, Gene? Really? It just confirms what we've known all along – that you're descended from lizards.

Watch the video after the jump.

I've always enjoyed jingles, you know, those catchy commercial tunes that get in your head and never leave. "Two all beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame seed bun." See, after all these years, it's still there. I wonder if Gene Simmons would have liked that McDonald's jingle?

We'll soon find out what the Kiss star likes in musical commercial craftsmanship because Gene Simmons has been tapped as one of the judges on the CBS reality show Jingles. It's a competition show, from producer Mark Burnett, he of Are You Smarter Than a 5th Grader, Survivor and The Apprentice fame. We'll just forget about the ones that didn't fly, like On the Lot (that was painful to watch), Pirate Master (unwatchable) and Rock Star: INXS (truly a train wreck).

Jingles should be pretty challenging for contestants; it's hard to fake it when it comes to writing words and lyrics. The winner gets a contract with an advertising agency and $100,000.

As long as their are celebrities, people will find odd ways to pay tribute to them. First, there was Jerry Seinfeld, who had a peanut butter sandwich named after him, and now the same honor has been bestowed on Jerry Springer, whose name has been given to a Carnegie Deli sandwich consisting of "pastrami, tongue, baloney, Swiss Cheese and Russian dressing." My guess is that they asked a blind man to make a reuben sandwich and this was the result. Sounds like an acquired taste to me, and a far cry from Seinfeld's peanut butter, honey, and cinnamon concoction. Maybe the sandwich is only part of the full dining experience, and to really appreciate it you need to have someone smashing a chair over your head and screaming at you to stop sleeping with their daughter's cousin's husband. The sandwich was created to celebrate the 3,000 episode of Springer's TV show.
