WATCH: Rob McElhenney Shows Off Bill Cosby Tattoo on Conan


The cast of It’s Always Sunny in Philadelphia were on Conan last night, when the discussion veered toward fans who had gotten tattoos of cast members painted on their bodies. From there, as they say, silliness ensued, with Charlie Day, Glenn Howerton and Rob McElhenney showing off some of their own (fake) celebrity tattoos—the worst being McElhenney, who had ink of Bill Cosby. As a joke, he scribbled an “R” between the “C” and “O” and drew a thick moustache on the face to disguise it as David Crosby. No one buys it, of course. Watch the clip above.
