Heh, I remember in my AP US Government class, we were talking about voter registration, and the Motor Voter program specifically. In case y'all don't know what that is, it's a program where people register to vote at the DMV when they get their drivers license. So here's how it went:
Teacher: "Does anyone know why the motor voter program was considered to be a failure?"
-Long awkward pause-
Teacher: "Anyone?"
-I raise my hand, teacher nods at me-
Me: "Because the DMV is always full of Mexicans?"
-Class starts laughing, teacher is glaring at me with the dirtiest look he can muster-
Teacher: "Jordan, you have lost your talking privelages for the next week"
Me: "You know it's true. The first thing they ask you at the DMV is if you're a US citizen!"
Teacher: "True..."
Me: "Hablas espanol?!"
-Class laughs again-
Teacher: "OUT!"
-Exit, stage left-
