little johnny jokes

Little Johnny returns from school and says he got an "F" in arithmetic.
"Why?" asks the father.
"The teacher asked 'How much is 2x3?' I said '6.'" 
"But that's right!" The father replied.
"Then she asked me 'How much is 3x2?'"
"What the heck's the stupid difference?" asked the father.
"That's what I said!" 

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!"
