For many people, choosing a tattoo takes a lot of thought and preparation. With something so permanent, many want to make sure it's something they truly love and would love on their body forever. Similarly, people sometimes think twice on sticking body parts into a glory hole, or in this story's case, "Whole Glory."
Tattoo artist, Scott Campbell decided to do tattoos on people in which they stick their arm through a hole in a wall and he then tattoos whatever he'd like on them. To him, it's more of an intricate, thoughtful process than people might think. And some of these tattoos are great! And some...not so much.
This idea leaves much to think about. For example, would you trust a stranger to permanently mark you with something that you have zero input on?
