Exactly how geeky are you? Here’s a quick test: Sexy Geek Jason Willmore (hi, Jason!) sent us a picture of his tattoo, which works as a sort of geekiness metric for people he meets.

I had a whole year in Iraq to come up with my ideal geek tat. The great thing is not only does it prove my geekiness, if someone knows who all the characters are it lets me know just how geeky they are.

Challenge accepted? Tell us which references you spot in Jason’s ink. :)
