Editor's Note: We ran this epic guide to athlete mustaches last year, but we decided to reissue it in honor of the first day Movember. Gentlemen: Mustache season is officially open.

Fact: Movember and its cousin, No Shave November, are the greatest thing to happen to facial hair since Tom Selleck. As you prepare to groom your lip lettuce into a handlebar, horseshoe, walrus, Chaplin, or fu manchu while offering free mustache rides over the next 30 days, let's pause a moment to remember the reason behind the season. Besides terrorists and other heinous criminals who commit crimes against humanity, there's nothing a man hates more than prostate and testicular cancers. This malicious disease has left far too many Dads and older Bros on the sidelines or out of the game way too early. According to the American Cancer Society, about one in every six men will be diagnosed with prostate cancer during his lifetime. Even with the chance of surviving increasing every year, this ultimate Bro-hater will claim about 32,050 men in 2010 alone. In an effort to kick prostate cancer's ass, last Movember the Prostate Cancer Foundation and the Lance Armstong Foundation organization raised $42 million, all thanks to men around the world growing and flaunting grizzly lip sweaters. Support the cause here.

As inspiration for growing your non-ironic Movember masterpiece, let's take a look at the 100 manlinest 'staches in sports history. We believe it's the most comprehensive list of sports mustaches in Internet history. Note: Sidney Crosby was never once considered for this encyclopedic round-up of iconic athlete facial hair. Let's face it, no matter how much Rogaine Sissy Crybaby injects in the off-season, he'll never be able to match the whiskers of his superjock brethren.
