Each month, all the contestants who get the highest score in the quiz go into a draw for a skull-and-crossbones T-shirt, perfect for Halloween, Piracy on the High Seas, or just general bad-taste dressing.
It comes in two sizes, large and XL, on white cotton. I've had the skull and crossbones motif enlarged since this photograph was taken.
