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 Yankees fan is next to profess his love for his team.

He yells, "This is for everyone!" and pushes the Red Sox fan off the
mountain.
