The news media may be fussing about President Obama's birth certificate, but what they really need to worry about is his thirst for brains. All kidding aside, these popular "Zombama" tees by Pop Monkey feature a zombified version of our Commander-in-Chief and are going into their third printing. Priced between $18 and $22, they're available in Small to XXXL sizes for guys and XS to XL for girls. If you want to make sure you get one, you can pre-order yours now and it'll ship in two weeks. What better way to honor the first black president than with a T-shirt that makes him look like the undead? [Via SpankyStokes]
