The line 'surprisingly well adjusted' in this tattoo comes from the show that Charlie Day is most famous for: "It's Always Sunny in Philadelphia". Some may know him as well, if not better, from his parts in the 'Pacific Rim' movies, but the sitcom is probably where most people saw him first. It's a good comment on the tattoo as well; Day has adjusted surprisingly well to life as a tattoo on someone else's body. Look how happy he is about it!
This is definitely a tattoo that belongs in the 'super lifelike' category. The work that the artist has done with light and shade to bring the image to life is incredible. Every line, crease and feature of Day's face has been captured perfectly. If it wasn't for the fact that it was in black and white (and clearly on somebody's upper leg), this could have been mistaken for an actual photo of the performer.
