Tattoos in Weird Places

Tattoos in Weird Places
There are a lot of weird places for tattoos. Or, let's say there are a lot of weird places that people have put tattoos. I'm not sure how good of an idea it is to put one on the inside of your lip, or on your tongue, but it has been done before.
I think a lot of people that are interested in weird places to put a tattoo may like the idea of having a tattoo, as well as having it in a non-obvious place so most people would not notice unless they told or it was showed to them.
Tattoos on the scalp or anywhere on your head under your hair would be a place easily hidden or shown. Of course, that would mean you would have to shave that part of your head and would have a huge impact on what kind of hairstyles you could have when showing your tattoo!
