Which one would you get?
What a compassionate bunch of weirdoes the It's Always Sunny In Philadelphia gang are. As audience members groaned over fan tattoos inspired by the show, the cast was more than willing to admit that they have some very real, permanent tattoos of performers who have inspired them. Charlie Day even has a tattoo of Glenn Howerton. Because of his work in Must Love Dogs.
The problem with tattoos is you want them to refer to something timeless. They don't all age well, as you can see with Rob McElhenney's David Crosby ink.
