McDonald's 1984 Olympics promotion

[1][2] In addition to the sponsorships and advertising, McDonald's prepared to repeat a successful giveaway promotion they deployed during the 1976 Summer Olympics in Montréal, Quebec, Canada, where customers were offered a chance to win products when the American team won a medal.

[1][3] As the Games started and the American teams conquered podiums, customers were enthusiastic about exchanging their cards for free food.

[5] Marketing experts estimate it in the millions of dollars, especially since the chain normally makes a generous profit on each of the Big Macs it was now handing out for free.

Like the McDonald's game, if the U.S. Olympic Team won gold in that event, the card could be redeemed for a free Krusty Burger.

On the final day of the Olympic Games, a furious Krusty appears on live TV, smoking and crying, calling his customers "pigs" and vows to personally spit in every fiftieth burger, to which Homer Simpson replies, "I like those odds!".

Several restaurants struggled to keep up with customers trading in their promotion cards for Big Macs, as the American Olympic Team raked in gold medals.
