Moustaches: they look good on men over 40. If you’re under 40 and you have a moustache, you’re probably a hipster who grew a terrible moustache on purpose or you’re a teenager who thinks that your slightly darkened upper lip makes you look older and, therefore, irresistible to women.
You might also be gay. For some reason moustaches have remained popular in the gay community even as they’ve lost fashion among most other men.
Regardless of who you are, if you’re under 40 there is a good chance that your moustache makes you look creepy. It’s not fair, but that’s just the way that it is. Moustaches on the under-40 crowd look creepy.
I’m oversimplifying, of course, but I think this gallery of moustaches at the Times Online provides a strong argument in favour of my point. The most compelling argument comes from Fred Macpherson, in the fifth picture, who says that his moustache makes him “feel a little like a sleazy children’s entertainer” and that people think he’s “mad or a sex offender.”
Why he doesn’t just shave it off is beyond me.
(Hat tip to Look at this fucking hipster for the link to the gallery.)

Hmm… I don’t find moustaches to be that prevalent in the gay community. Maybe beards and goatees in the bear community, though.
I think you’re right, Todd. I was thinking about that as I reread the post and I have no idea where I got that idea. The only gay men I know who have moustaches fall into the over-40 group.
