Two calendars, two dozen critical thinkers in various states of undress
There are Skepchick and Skepdude versions available1 and all money goes to good skeptical causes. Intrigued as I am by the presence of James Randi, I think Skepchick’s the one for me. Last year’s version sold out rapidly – well before I heard about it – so it might be worth getting in a pre-order before early November if you fancy one. Anybody worried about exploitation should see this forum thread and last year’s photos.
