Sorry, Simpsons. This time, real life did it.
In 1984, the Olympics came back to the United States, and McDonald's went all-in with their sponsorship of the games. To show their confidence in the U.S. Olympic team, Mickey-D's came up with the "If the U.S. wins, you win!" promotion. Customers got scratch pieces with an Olympic event printed on them. If the Americans won a gold, silver or bronze medal in that event, the customer would get a free Big Mac, fries or Coke, depending on the medal.
"Now with steroids!"
Now, no business goes into a "win a free ___" promotion without having a fairly specific idea of how much free merchandise is going to go out the door. McDonald's probably looked at the U.S. medal count from the last games we had participated in, in 1976. In that year, the U.S. won 94 medals, 34 of them gold. After all, it was the Soviets and their allies who dominated the games every time (in 1976, Russia won 125 medals, and East Germany won 90, with 40 gold medals).
