The teacher said to his class one, "Please stand up, anyone who thinks they're st*pid"
Nobody stood up so the teacher said, "I'm sure there are some st*pid students in this class!"
At this point little Johnny stood up.
The teacher said, "Oh Johnny!So you think you are st*pid then?"
Little Johnny replied, "No, it's out of compassion for you ma. I just felt bad that you were standing up on your own."
