Counterfactual sports t-shirts: Immediately after a major sports championship such as a Super Bowl, the winners get pre-made t-shirts proclaiming their victory. But what happens to t-shirts that were made in case the other team had won? They get sent to Africa. It sure would be a cool collectors' item to have all 4 of the "Buffalo Bills Super Bowl Champion" counterfactual t-shirts for 1991-1994.
