Sometimes a fan will go to great distances to show they are a celebrities' number one fan. Some watch all of their movies and hangs posters of them all over the walls; some send letters, and others, the intense die hard fans, get portrait tattoos of their favorite superstar.

Neil Patrick Harris was on Conan O'Brien last night, were Coco showed the actor a picture of a tattoo a fan got of him. It's NPH face, suavely posing as this character on 'How I Met Your Mother"; the location is unknown but NPH nailed it with this comment about the tattoo's shading: “Why are my fingers bleeding? It must be the inner thigh."
