Nothing says, "Happy Birthday, USA!" like a form-fitting pair of stars 'n' stripes shorts and an American boxing the shit out of a Russian in his own country. These officially licensed Balboa shorts hit--powerfully jab, really--the free market from the film Rocky IV's final fight scene, during which our nation's favorite underdog, hero, and man of questionable intelligence comes to blows with Ivan Drago to avenge the death of his friend Apollo Creed. It's OK if you just wear them to sleep in or use as a prop to make jokes about "raising the flag" though.
Enjoy your 4th of July. Be safe and don't tie firecrackers to the legs of friends who pass out drunk. Or at least if you do keep a throwable fire extinguisher nearby and don't say that I gave you the idea.
