Tucker Carlson and good pal Kid Rock had another friendly conversation on Fox News on Friday, with one topic of discussion being “testicle tanning.” The subject had been raised earlier in Carlson’s show by Andrew McGovern, an Ohio-based fitness professional who was brought on to help answer Carlson’s question, “How do you reverse the effects of falling testosterone?” One of the solutions McGovern offered was red light therapy, which, when Carlson asked, he said includes “testicle tanning.”

Rock had apparently been listening along, because when Carlson addressed him minutes later, the first thing the musician said was, “Dude, stop! Testicle tanning? Come on. I haven’t heard anything like that in a long time.” The Fox News host replied, “Open your mind, Bobby!” He then asked, more seriously, “Don’t you think at this point when so many of the therapies, the paths they’ve told us to take, have turned out to be dead ends that really hurt people, why wouldn’t open minded people seek new solutions?” Rock demurred: “I don’t know what the hell is going on in this world. I’m not even sure if I understood that question. But some days you just want to stop this planet and let me off.”
