On your marks(Cutie marks vs Tattoos)

So I just watched "On your marks" and I LOVED the first two-three minutes of the CMC just sitting there staring at their new cutie marks. As I was watching this, all I could think was that I did the exact same thing when I got my tattoo. Literally anyone with a tattoo would probably say the exact same thing as it has to do with sudden changes to your body image. So you end up just sitting there staring at it for DAYS on end before your brain finally adjusts to it. Come to think of it I don't think I've seen any HIE fics where the human has a tattoo. I feel like that's a loss because some pony's might think it's a cutie mark and I feel like explaining the process of getting a tattoo to ponys might be kinda funny. Anyone know of any fics like that? If so tell me about them.
