Four NY sports fans were climbing a mountain one day.
Each was a fan of a different team, and each proclaimed to be the most loyal of all fans of their team. As they climbed, they argued as to which one of them was the most loyal of all. They continued to argue all the way up the mountain, and finally as they reached the top, they vowed to prove their loyality..
The Mets fan hurled himself off the mountain, shouting,
"This is for the New York Mets!"
and he fell to his doom.
Not wanting to be out done, the Jets fan threw himself off the mountain shouting
"This is for the Jets!"
Seeing this, the New York Islanders fan walked over and shouted,
"This is for everyone!"
and pushed the New York Rangers fan off the side of the mountain.
