Twenty-one members of the Clown Conservatory Class of 2008 posed for the 2009 Naked Clown Calendar, which is being sold to raise funds for a teacher who was paralyzed by MS and others afflicted with the disease, the Contra Costa (Calif.) Times reported Thursday.

"Our goal was to create this sort of craziness in your mind," said Chad Benjamin Potter, the clown who organized the project. "When you think of clowns you think of costumes and makeup and hair. When you think naked clowns, that's something else entirely."

Potter said the clowns who posed for the calendar did manage to preserve some modesty by keeping their naughty bits covered.

"But of course we wanted to do something that everyone can enjoy," Potter said "I am going to sell (the calendar) to my grandmother and I also want to sell it to my niece and my nephew."
