There is a Yankee fan, a Red Sox fan, a Marlins fan and a Cubs fan climbing up to the top of a mountain talking about how loyal they are to their team and how they would do anything for them.
Once they reach the top of the mountain the Marlins fan screams, "THIS IS FOR THE MARLINS" and jumps off.
The Cubs fan screams "THIS IS FOR THE CUBS," and he, too, jumps off of the mountain.
Finally the Red Sox fan screams, "THIS IS FOR EVERYONE" and pushes the Yankee fan off!!
