There is a Yankee fan, a Red Sox fan, a Cubs fan and a Marlins 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 Cubs fans screams "THIS IS FOR THE CUBS" and jumps off.

The Red Sox fan screams "THIS IS FOR THE RED SOX" and he too jumps off the mountain.

Finally, the Marlins fan screams "THIS IS FOR EVERYONE" and pushes the Yankee fan off.
