Ever since a group of U.K. ambulance workers set sirens blaring with a too-sexy fundraising calendar, we've noticed a full-fledged phenomenon of bizarre sexy calendars. It seems like there's no profession, minority group, hobbyist club or demographic that hasn't bared it all for fun or profit (or both).

From naked clowns to sexy girls with coffins, there's more than enough weirdness to last from January to December.
