Nerd hero Nathan Fillion warns of grave gamer affliction

Listen up gamers, our very favorite nerd hero has something important he'd like to talk about.

That's right, Nathan Fillion — star of "Firefly," "Castle," "Dr. Horrible's Sing-Along Blog," and several "Halo" games (not to mention the should-be star of the forthcoming "Uncharted" movie) — has bravely stepped up  to offer the above public service announcement about a very real condition that affects millions of gamers every year.

It's called "swamp ass" but it's also known as mudd butt, cabbage crack and the great putrid divide. And it's especially important that we address it openly now that the hot summer months have set in and swamp ass can quickly turn into ... well, an even more unsavory affliction.

Live in sweaty shame no longer, my friends. Fillion is not just a Hollywood star, he's a gamer ... and he understands your pain.

Most importantly, he implores you: take care of your undercarriage.
