A teacher asks her students if they were Oakland Athletics fans. All of the hands go up except for one student.

"Okay, Bobby. What team are you a fan of?"

"The New York Yankees."

"Why's that?"

"Well, my parents are both Yankee fans, so I'm a Yankee fan too."

"That's not a good answer, Bobby. If your parents were both morons, would you be a moron too?"

"No, that would make me an Athletics fan!"
