I did it last november. my buddies and I had a no shave november and then half way through that we were gonna do moustache december. A bunch of my friends made it both months but I only made it through november. I don't grow moustaches.
me and my roomate are gonna do it, i think part of the reason he wants to is to piss off his girlfriend, shitty thing is she's my roomate too so is probably gonna be bitchy the whole time (more than usual)
