In other news, I was breathing distance from semi-tattoo celebrity Angelina Jolie last night and got a lot of good pictures of her tattoos last night. The dragon she had removed (Billy Bob) looks like a faint smudge up close and I don't see why she wouldn't just tattoo right over it (she sort of did towards the top of the tattoo).
