Yes, my geek is reflected sartorially. I now have quite the collection of T-shirts with a geek theme, but they are rarely seen in public, as they’re worn as a layer under long sleeves for work.
Want to measure your greek cred? You get a point for each correctly identified reference on each shirt. (I’ll give you two, and clues for two more: the University of Mars shirt is from Lowell Observatory. The geek rationale of the plain green T-shirt may be difficult to place at first: it is from scottevest, and filled with hidden, Batman-like pockets. As for the clues: two of the shirts are from the wonderful Last Exit To Nowhere.)
