In 1976: Owner Ted Turner of the Atlanta Braves offers perhaps one of the goofiest promotions of all time to fans attending the game versus the Mets. First, 34 couples were married in a ceremony at home plate. Then, Turner held a card for his fledgling Championship Wrestling league on the field; thus the (I guess) appropriately named Headlocks and Wedlocks promotion.
In 1979: As strange as Turners promotion might have been, it doesnt hold a candle (or should I say blowtorch?) to a charter member of the Sick Promotions Hall of Fame: Disco Demolition Night at Chicagos Comiskey Park. The White Sox were playing a doubleheader against the Detroit Tigers, and White Sox owner Bill Veeck encouraged fans to exchange their unwanted disco records for a dollar admission to the game. Fans also brought records into the game and were tossing them like Frisbees. It quickly got ugly, as Chicago DJ Steve Dahl blew up a box of disco records in center field (and tearing a hole in the field). Fans quickly rushed the field, started their own fires, and police in riot gear had to clear the field. The White Sox forfeited the second game of the doubleheader.
