Gump Tees are nerdy and proud, if its mathematical they’re on the case. They offer a selection of funny nerd t-shirts in sizes S-XL for guys all at $18 each. Their Calculus Hero Tee stands out by a mile…

Calculus Hero Tee

A great spoof on Guitar Hero, which for anyone over 30 with even the slightest ability in music… totally sucks. At least music games seem to be moving on now, as in you can play or rather learn to play ‘real’ instruments. In the meantime, one talent that has evaded me since the age of 11 is calculus, now that is a doozy. If the world ran on the lines of brains over beauty and brawn, every nerd would be a hero! Get this kewl tee for guys in sizes S-XL for $18.

You can get a whopping 25% off all the tees at SocialFabrik.co.uk this month in their January Sale. Just enter the code ‘JANUARYSALE‘ at the checkout!
