A first grade teacher explains to her class that she's a Cubs fan. She asks her students to raise their hands if they're Cubs fans, too. Not really knowing what a Cubs fan is but wanting to be just like their teacher, the students launch their hands into the air. There is, however, one exception: Little Johnny doesn't go along with the crowd.
The teacher asks him why he's decided to be different. "Because I'm not a Cubs fan," Litle Johnny says.
"Then what are you?" asks the teacher.
"Why, I'm proud to be a Sox fan," boasts Little Johnny. The teacher is a little perturbed now, her face slightly red. She asks Johnny why he's a Sox fan. "Well, my mom and dad are Sox fans, so I'm a Sox fan, too."
The teacher is now very angry. "That's no reason!" she says loudly. "What if your mom was a moron, and your dad was a moron. What would you be then?"
Little Johnny pauses, then smiles. "Why, then," he says, "I'd be a Cubs fan."
