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.
