In 1995: One of the worst ideas for a promotion (right behind Disco Demolition Night and 10-Cent Beer Night) took place at Dodger Stadium. The Dodgers thought it would be a good idea to hand out free baseballs to all fans, but didnt follow one of the golden rules of promotions:
Dont give away anything the fans can throw on the field and possibly kill someone
The Dodgers failed to listen, and fans repeatedly tossed hundreds of baseballs onto the playing field after disagreeing with a few umpiring calls and Dodger ejections during a game against the St. Louis Cardinals. After the third time the umpires stopped play, crew chief Jim Quick felt he had no choice but to forfeit the game to the Cardinals in the ninth inning, 2-1. The Dodgers protested, but the N.L. upheld the forfeit the following day. Another umpire blamed L.A. manager Tommy Lasorda for inciting the crowd, saying, Lasorda instigated the whole damn thing by waving his fat little arms out there. link
