Gene Simmons Dealt with Kidney Stone During Final KISS Show

Gene Simmons is one tough demon. Somehow, he managed to rock his way through the final KISS show while dealing with a kidney stone.

Following the show, which streamed via PPV.com, there was some live backstage footage of the band fresh from the stage. Host Allison Hagendorf was speaking to Simmons when he made the painful revelation.

"Believe it or not, my hand to God, I was just passing a huge kidney stone," said Simmons. "I was peeing in the bathroom, and I felt it burning on the tip of my c-ck, but it did not come out. So, it's right at the head of my schmeckle." (For those not fluent in Yiddish, "schmeckle" means "little penis.")

An unidentified man backstage then yelled, "The world's watching this, Gene!" However, Simmons was completely unphased.

"You've seen my facelift on our show," Simmons responded, referring to how he and wife, Shannon Tweed, got his-and-her facelifts on their reality show Gene Simmons Family Jewels. "I don't care! But my big kidney stone is right on the head of my schmeckle. You think I could make a few bucks and put it on eBay?"

We seriously wouldn't be surprised if Simmons put the kidney stone up for auction. You just know someone would buy it. Regardless, we hope that he has since passed that stone and wish his schmeckle the best.
