Stupid Johnny

A new teacher was trying to make use of her psychology courses. She started her class by saying, "Everyone who thinks you're stupid, stand up!"

After a few seconds, Little Johnny stood up.

The teacher said, "Do you think you're stupid, Little Johnny?"

"No, ma'am, but I hate to see you standing there all by yourself!"

Stupid Johnny - Psychology techer asks the stupid kids to stand up.
When no one does, Johnny stands up and gives one to the teacher.
