What is simply November to you is so much more to so many men around the world. Sorry ladies, you don't want to be a part of this one. Leave Movember to the men. For once all the "trick or treaters" are tucked in bed and the clocks have fallen back, lots of bold gentleman are going to embark on a follicle adventure, celebrating the most versatile of facial hair - the moustache. According to the official Movember website the rules (oh yes, there are rules) are simple:

1. Once registered each Mo Bro must start November 1st with a clean shaven face. 2. Then, for the entire month of Movember each Mo Bro must grow and groom a moustache according to these rules: 1. There is to be no joining the Mo to the side burns - that's a beard. There are no beards. 2. There is to be no joining of the handlebars on the chin - that's a goatee. 3. A small complimentary growth under the bottom lip, aka a tickler, is allowed.
