First Grade Teacher

A first-grade teacher explains to her class that she is an Blue Bulls fan. She asks her students to raise their hands if they are Bulls fans too. Not really knowing what a Bulls fan was, but wanting to be liked by their teacher, their hands fly into the air.
There is, however, one exception. Kelly has not gone along with the crowd. The teacher asks her why she has decided to be different. "Because I'm not a Bulls fan" she reports.
"Then," asks the teacher," What are you?"
"I'm a Sharks fan," boasts the little girl.
The teacher asks Susie why she is a Sharks fan.
"Well, my Dad and Mom are Sharks fans, so I'm a Sharks fan too," she responds.
"That's no reason," the teacher says. "What if your mom was a moron, and your dad was an idiot. What would you be then?"
Kelly smiles and says, "Then I'd be a Bulls fan."
