The cast of characters who lurk around Paddy’s Pub are some seriously shady human beings, and not so long ago people with tattoos were seen as shady and untrustworthy by "polite" society.
So it only makes sense that fans of It's Always Sunny In Philadelphia would want to commemorate their favorite shady characters Charlie, Mac, Dennis, Dee and Frank with colorful tattoos!
The gang from Sunny recently paid Conan O'Brien's show a visit, where they took a look at some interesting fan tattoos inspired by the show before showing off their own regrettable ink stains tattoos. Tattoos based on TV shows never go out of style...until about five to ten years after the show is canceled!
