Kurwood Derby - The mythical hat featured on episodes of the animated cartoon ROCKY & HIS FRIENDS/ABC/1959-61 (a.k.a. THE BULLWINKLE SHOW). The Kurwood Derby (first seen in 1961 in 26 (3:30 minute) episodes of "Missouri Mish Mash") was a famous hat that made anyone who wore it, the "smartest man in the world." Legend tells that a cave man who first wore it immediately went out and invented the wheel. The hat resurfaced throughout the ages on the heads of such people as Aristotle, Philip of Macedonia, Ghenghis Khan, Julius Caesar and Elvis Presley. The hat's last known owner was a Princeton  professor who put the hat on his head and remarked "E=MC squared." Pottsylvanian spies Boris Badenov and Natasha Fatale were instructed by their Fearless Leader to find the hat. For whoever owned the hat would "RULE ZA VERLD!" Bullwinkle J. Moose (who could never get the "hat" to work right) was the current owner of this magical bowler originally created by a race of Moonmen who were the progenitors of square-headed space aliens named Gidney and Cloyd. TRIVIA NOTE: The name "Kurwood Derby" was a parody of the name of a popular celebrity of the time named Durward Kirby who starred on the variety program THE GARRY MOORE SHOW/CBS/1958-64 and later on CANDID CAMERA (1961-66). When Mr. Kirby's lawyers wrote Jay Ward, the creator of the cartoon series, and demanded that he stop using the name "Kurwood Derby" because it spoofed the celebrity's name, Jay Ward encouraged the lawyers to sue because. he could "use the publicity." (Of  Moose and Men: The Rocky & Bullwinkle Story, a documentary aired on PBS in 1991). While searching the internet for the "Kurwood" Derby use also the variations of  "Kirward," "Kerwood" and "Kirwood" for a comprehensive search.
