I'm afraid this thread is likely to be gender-specific...
As many gentlemen here will know, there's a growing charity fundraising lighthearted event - grow a moustache in November. A short google will inform.
I think the rule is, start clean-shaven on Nov 1. Just hacking back the existing fronds apart from the upper lip doesn't qualify. Then the bushy and sculpted growth is viewed for judgement at the end of the month.
Any past participants care to comment? Any new participants care to commit?
I'm in the land of proud upper lip stuff at the moment, so I might!
