I've got hyper-intelligent, genetically-engineered apes on the brain, after hearing so much about Rise of the Planet of the Apes. And these tees from Ex-Boyfriend are the perfect thing for my mood.
Ex-Boyfriend has a great collection of designs that combine geeky themes with bizarre cuteness. Plants eating cities, while bunnies flee! Pirate bunnies on the high seas! Apes fighting planes on top of rhinos! It all makes perfect sense.
You can pick these awesome shirts up at Ex-Boyfriend, for $25 a pop. Many also come as hoodies.
