We've covered fantastic design-led t-shirts from the likes of Threadless and Design By Humans many times, but sometimes you need a tee that shows off your inner geek. Here we've selected some of the geekiest T-shirts ever spotted in the wild.

Just being seen wearing one of these classics can elevate you to the heady heights of geek chic. Prepare for the awesomeness that ensues!

Bat Boy proves Riemann Hypothesis

This T-shirt combines pop culture and mathematics in a perfect convergence of geekery.

Bat Boy of Weekly World News fame proves the Riemann Hypothesis, a mathematical conjecture about the distribution of the zeros of the Riemann zeta function which states that all nontrivial zeros of the Riemann zeta function have real part 1/2.

And he has pointy teeth! Pointy teeth are cool.

Ninja Code

Here we have an example of a typical geek obsession (ninjas) combined with another geek obsession (coding).

If you understand the humour of this shirt, your geek credentials are confirmed!

Otherwise, ask a ninja.
