I don't know if it was a running joke but since the big birthday show that Stern did when Mayer performed, Mayer said he'd do the show. That was a while ago. I think in 2014 or 2013. So MarksFriggin would plug him as an upcoming guest. Since been removed as of, maybe a week ago? http://www.marksfriggin.com/index2.htm Love MarksFrggin, btw.
