jokes :: bush/texas joke

There's a teacher in a small Texas town. She asks her class how many of them are Bush fans. Not really know what a Bush fan is, but wanting to be liked by the teacher, all the kids raise their hands except one boy, Johnny. The teacher asks Johnny why he has decided to be different. Johnny says, "I'm not a bush fan."
The teacher says, "Why aren't you a Bush fan?"
Johnny says, "I'm an Al Gore fan" , The teacher asks why he's an Al Gore fan.
The boy says, "Well, my mom's an Al Gore fan and my dad's an Al Gore fan, so I'm an Al Gore fan!"
The teacher is kind of angry, because this is Texas, so she says, "What if you're mom was a moron and you're dad was an idiot, what would that make you?"
Johnny says, "That would make me a Bush fan."
