Gentlemen, dudes, guys and assorted testosterone-filled males, we need your upper lips -- it's time to fight some cancer!

In an effort to spruce up our reputation and our appearance, Asylum editors are pledging to support not one but two mustache-based charities this fall. We've recruited a whole mess of Web sites to join us: AskMen, Men's Fitness, World of Isaac, The Bachelor Guy, Switched, Fanhouse, Noise Creep, Asylum UK (duh), Urlesque, Moondog Sports, Chris Illuminati, SEC Rivals, Midwest Sports Fan, Cool Material, Dave and Thomas, Burbia, Stephen Bailey, Gear Patrol, Yep Yep, Next Round and, of course, The American Mustache Institute.

Would you like to participate? You've got two choices:

1. Mustaches vs. Cancer starts October 5 and lasts for 56 days. Proceeds go to the Memorial Sloan-Kettering Cancer Center.

2. Movember goes throughout November, with money raised benefiting prostate and testicular cancer foundations.

All you have to do is register with your charity of choice and ask friends and family to donate money to see pictures of you looking increasingly more awesome. If you decide to participate in either charity, check back in at Asylum later this month for free swag and contests. Also, whether or not you participate, you're invited to the Stache Bash.
