i knew a guy with a marvin the martian tat, i always thought that was pretty cool.
i knew this guy, he read those tat mags, and spent allot of time picking out a tat, shaved his head, and got this jester looking thing tattooed on the back of his mellon. road a box car to Arizona, and no one would talk to him, turned out that he didn't know he got the face of a Native American Demon on the back of his melon. lol
my wife got one with Hindu Letters for our kids, as she's of East Indian descent. But she did some research, to get it correct.
point is, what ever you do, it wont ever go away, so make sure its what you want.
