Sharing Day, Tattoo Edition

While perusing this "50 Awesomely Nerdy Tattoos" article, I got to wondering what you all would want if you were forced at gunpoint to get a tattoo (or even just asked nicely!) revolving around something nerdy or geeky.

I don't personally have any tats, as I am too fat, too hairy, and too old to have it make sense. Although I have considered getting hair tattooed on my head, that might work. Not, like, long hair, but stubble, you know, so it would look like I had just shaved my head and it was growing back stubbly, only all over instead of just in the horseshoe shape.

But I digress.

Because I like to get to know you folks better, I like to have these "Sharing Days" every now and then where I ask a question and you answer in comments. This time around, it's:

If you had to get a tattoo on a geeky or nerdy theme, what would you get and where would you put it?

In return, if you wish you can ask me whatever you like and I'll try my best to give an answer. Note that by no means are you required to ask me something in order to answer the question at hand, but that if you do want to ask me something, you have to have answered the question. I'm exhausted just typing that.

I look forward to hearing your replies!

Oh! And my favorite one from that site is probably this, because I could totally see typing away and then catching a glimpse of it out of the corner of my eye and instantly being all WHOOOSOSOOSH and I AM YOUR FATHER and FEEL THE POWER! Anything that increases the entropy of the universe is AOK in my book (clearly).

Edited to Add: Geez, I forgot to answer the question myself! I would probably get a medium-sized Superman insignia on my right deltoid (such as it is). Although that light saber tat on the finger is pretty rockin' ... Only I'd get one on the outside of each index finger so I could finger-fight myself.
