Dubbed the “baddest little show on Earth,” the Extreme Midget Wrestling Federation pits little guys with muscles up against one another. The sport is pretty popular too — matches generally draw between 300 and 5,000 fans and tours have taken the little fellas to Europe, South America and Japan. Tonight’s bout begins at 8 p.m. at House of Blues. Tickets are $10 in advance, $13 at the door. (Jeff Niesel)
