Four baseball fans - a Cubs fan, a Cardinals fan, a Red Sox fan, and a Yankees fan - are climbing a mountain and
arguing about who loves his team more.
The Cubs fan insists he is the most loyal. "This is for the Cubs!" he yells, and jumps off the side of the mountain.
Not to be outdone, the Cardinals fan shouts, "This is for the Cardinals!" and throws himself off the mountain.
The Red Sox fan is next to profess his love for his team. He yells, "This is for everyone!" and pushes the Yankees fan off the mountain.
