Five Detroit Tigers fans, Al, Ben, Carl, Dan, and Edgar, are watching a home game for the Tigers. Of course, the Tigers easily lose, and the five fans leave the stadium angrily.
"If those players had played better, we could have won," said Al.
"Don't blame the players, blame the coach," said Ben. "If he had trained the players better, they would have played better."
"Those players couldn't play a decent game if their lives depended on it," said Carl. "But it's not the coach's fault they're on the team, it's the general manager's fault."
"Well, I think it was the umpire's fault," said Dan. "I think he was biased against the other team and gave them an advantage."
Al, Ben, Carl, and Dan get into a huge argument over who to blame: the players, the coach, the manager, or the umpire. Finally, Edgar gives a loud whistle, and everyone stops arguing and looks at him.
"People," he says, "the fault lies neither with the players, nor the coach, nor the manager, nor the umpire, but with our parents."
"Our parents?" asks Al.
"What do you mean?" asks Carl.
"Well," explains Edgar, "if we had been born in Boston instead of Detroit, we'd be fans of a much better team."
