Movember starts November 1st. Rules: 1. Register here. 2. When you emerge from your Halloween-party hangover this Sunday, shave. 3. Grow and groom a moustache for the entire month. Dress codes and formal portraiture be damned! It's for charity!

Remember:
-There is to be no joining the Mo to the sideburns. That's a beard.
-There is to be no joining of the handlebars on the chin. That's a goatee.
-A small tuft is all allowed under the bottom lip (aka, The Tickler).
-Document your stache's progress with the Mo-Mento Maker, a Facebook app created by Movember sponsor Pepsi Max!

To get you inspired, here's a gallery of some of last year's most excellent 'staches.
