Back in the early 1930s, C.D. "Bigboy" Blalock of Louisiana State University&md;a six-foot-six-inch giant of a boxer&md;was taking on a stocky fellow from Mississippi State. In the second round, Bigboy let lose a roundhouse. The Mississippi man stepped in, and his head caught Bigboy's arm inside the elbow. With the opponent's head acting as a lever, Bigboy's arm whipped around in almost full circle, connecting with haymaker force on Bigboy's own chin. He staggered, grabbed the rope, walked almost all the way around the ring, and then fell flat for the count&md;the only prizefighter who ever knocked himself out with a right to his own jaw.
