Josh Gibson, the great catcher and slugger of the Negro Leagues in the days of segregation, comes up in a game in Pittsburgh and crushes a ball. It goes so high that everybody loses sight of it. Nobody sees it come down. Eventually the umpire rules it a home run and the game continues.
Next day the same two teams, with the same umpire, are playing again, but this time in Philadelphia. Gibson comes up to bat again, and suddenly a ball comes whizzing out of the sky, and the center fielder runs over and makes the catch.
The ump turns to Gibson. "Yer out -- yesterday, in Pittsburgh."
