Stand Up!
Published Jan 01, 1900

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 Ralphie stood up.
The teacher said, "Do you think you're stupid, Little Ralphie?"
"No, ma'am, but I hate to see you standing there all by yourself!"
