Teacher: Now class, if you are dumb, please stand up.
Class: no one stands up.
Teacher: Oh c’mon. I know someone over here is dumb. *teacher waves her finger around the left side of the room*
Little Johnny: stands up
Teacher: Oh, Johnny, you think you’re dumb?
Little Johnny: No, I just feel bad you’re standing alone.
