"A cow lying on her side is not immobilized" beach towel

Annie Rauwerda, the intrepid miner of the "Depths of Wikipedia" (and Boing Boing contributor) is supporting her outré editorial offerings by selling this brilliant beach towel emblazoned with a relevant image and caption from the "Cow tipping" entry on Wikipedia.

Even if you are lying on this towel, you too can rise whenever you choose, assuming you are healthy.
