"I am a Yankees fan," a first-grade teacher explains to everyone in her class. "Who likes the Yankees?"
Everyone raises a hand except one little girl.
"Anna," the teacher says surprised, "Why didn't you raise your hand?"
"I'm not a Yankees fan."
"Well, if you are not a Yankees fan, then what team do you like?"
"The Red Sox," Anna answers.
"Why in the world are you a Red Sox fan?"
"Because my mom and dad are Red Sox fans."
"That's no reason to be a Red Sox fan," the teacher replies, annoyed. "You don't always have to be just like your parents. What if your mom and dad were morons? What would you be then?"
"A Yankees fan."
