Was he the guy in Li’l Abner?
He runs the bar in The Simpsons, no wait that’s Moe Syzlak
Li’l Abner is what came to mind for me as well. From the nets (Sure fits! Maybe his parents named him after the character!!):
Joe Btfsplk was a character in the satirical comic strip Li’l Abner by cartoonist Al Capp (1909–1979). He is well-meaning, but is 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.
