A new teacher was trying to make use of her psychology courses. She started her class by saying, "Everyone who thinks he's stupid, please stand up!" After a few seconds, little Johnny stood up. The teacher was surprised, but realized this was an opportune moment to help the poor child. "Do you think you're stupid, Johnny?" she asked. "Why do you feel so my dear child"? "No, ma'am," Johnny replied, "but I hated to see you standing there all by yourself!"
