Humor found somewhere else on the Internet.
Four baseball fans, each from a Major League city, are climbing a mountain. On the way to the top, each is arguing about how loyal they are to their team, and what they would do for their team.
As the climb progresses, the odds increase. Upon reaching the top, the Red Sox fan shouts, “This is for the Sox!” and hurls himself off the top.
Not to be outdone, the Braves fan yells, “I love Atlanta- this is for the Braves!” and he jumps off, too.
A moment goes by… Suddenly the Mets fan shouts, “This is for everybody!” and pushes the Yankees fan off.
