Remember the naked rowers? How could you forget those butts! Each year, the University of Warwick men's rowing society puts out a nude calendar for a good cause, with portions of the money raised helping to fight homophobia.

For the second year, the women of Warwick have gotten in on the action too, posing au natural to raise money for Macmillan Cancer Support. And so far, they have sold some 1,500 copies and raised more than £3,000 for charity.

But Facebook has removed their page, claiming they breach the "pornography" policy.
