Gorilla Warfare

Love this. It comes from the site Arm the Animals, which has a whole series of shirts with animals and arsenals (and donates to animal charities). The "occupy" meme is my fave.

Make Awkward Sexual T-Shirts

A friend of mine bought me this shirt for my birthday, and it's the best.

It straddles the line of being hip enough to wear to a club where you can wear your emo little heart on your sleeve, but also goofy enough to wear to that family backyard barbecue. Plus it's sky blue! Perfect for the remaining months of summer.

Also, I just want to give Raygun a shoutout. It's an adorable shop full of inside jokes about Iowa that I don't quite get. ("Quit playing Ames with my heart." Huh?) But it also features great shirts like this.
