Warning: stomaching this live perfromance from the Swedish acapella group Visa Röster performing an interpretation of the C64 game music International Karate will level up your inner nerdiness by 1000 points. Proceed with caution, and make sure no women whom you ever aspire to sleep with are anywhere near you. Or men, if that's your thing. All jokes aside, I can't quite put my finger on why this one was particularly painful to watch despite the cool Karateka overlay. Anybody else want to fist the blonde?
