The cast of It’s Always Sunny in Philadelphia joined CONAN and Andy on the couch for a little comedy jam session yesterday. The gang discussed their fan’s obsession with show in the form of some amazing body art. The cast was a wee bit shocked by how far some fans go to show their loyalty. However, it turns out Glenn Howerton, Charlie Day and Rob McElhenney had a few tattoos of their own to show the crowd. Enjoy!

Mentions: Watch CONAN weeknights 11/10C on TBS.
