From Wikipedia The Green Weenie was a sports gimmick co-created by Bob Prince (1916 - 1985), the legendary broadcaster for the Pittsburgh Pirates Major League Baseball team, and Pirate trainer Danny Whelan. It was most popular during the 1966 baseball season in Pittsburgh, Pennsylvania, USA. The Green Weenie was a green plastic rattle in the shape of a hot dog, which when waved at opposing players, purportedly put a jinx on them. On the contrary, when waved at Pirate players, it bestowed good luck. The superstition began during a 1966 game against the Houston Astros, when Danny Whelan shouted from the dugout at Astros' pitcher Dave Giusti, "You're gonna walk him!" while waving a green rubber hot dog in the direction of the pitcher's mound. Giusti did walk the batter, and the Astros lost the game. During the next game's broadcast, Prince quizzed Whelan about the frankfurter incident, and the gimmick was born. Within weeks, Green Weenies were being sold to fans at Forbes Field.
