Joe Btfsplk was a character in the long-running comic strip "Li'l Abner" by cartoonist Al Capp....the world's worst jinx, bringing disastrous misfortune to everyone around him. A small, dark rain cloud perpetually hovers over his head to symbolize his bad luck. Hapless Btfsplk and his ever-present cloud became one of the most iconic images in Li'l Abner.
