Show your love for Guitar Hero by (1) learning how to play all of the game's songs on Expert --blindfolded-- and (2) by buying these Guitar Hero boxers, which were a surprise hit on Black Friday.

Good luck finding them, though. We spotted a single pair of the red boxers adorned with electric guitars (rolled up in a guitar-shaped gift tin) on sale at Kmart. The rock 'n' roll skivvies were priced at $8.99, and there was a single crumpled tin left on the shelves.

We can only imagine people rushing in for "door buster" bargains on flat-screen TVs, then stopping to chuck this novelty underwear into the cart as they race to the checkout counter. We checked for them online later and only found them listed (and sold out) on Kohls and Sears' Web sites.

You'll have more luck finding the other video game-themed skivvies that hit stores this season -- boxers that pay homage to Halo, Xbox 360, PlayStation 3 and Nintendo Wii -- each with their own gift tins. Unlike the Guitar Hero boxers, there are still plenty of these other gamer-centric underwear available online and in big box retail outlets like Target and Kmart. We're already rolling our eyes in anticipation of the Nintendo fans who will don a pair just to yell, "Hey, look at my Wii!"
