Ah, this reminds me that I have two tattoo stories to share!
The first, and by far less interesting, is that my wife now has one. It’s something she's wanted since high school. It is a combination of a child's knot/symbol for the trinity and a Star of David.
The other, more interesting story, is that we visited Portland, Oregon earlier this month. While riding around on MAX, looking for stuff to do, the fellow sitting across from us heard our discussion and chimed in with his help. He even got off the train and showed us to an apparently famous bookstore. The most amusing thing was, though that he had "NERD CORE" tattooed on his knuckles, and had a D20 tattooed on the back of his right hand.
