Teaching Arithmetic

A teacher was having trouble teaching arithmetic to Little Johnny. So she said , "If you reached into your right pocket and found a nickel, and you reached into your left pocket and found another one, what would you have?"
"Somebody else's pants," said Little Johnny.

Little Johnny and Geometry

Teacher: "Little Johnny, give me a sentence using the word, 'geometry.'" Little Johnny: "A little acorn grew and grew until it finally awoke one day and said, 'Gee, I'm a tree.'"

Little Johnny - Stupid

A new teacher tries to make use of her psychology courses. The first day of class, she starts by saying, "Everyone who thinks they're stupid, stand up!" After a few seconds, Little Johnny stands up. The teacher asks, "Do you think you're stupid, Johnny?" "No, ma'am, but I hate to see you standing there all by yourself."
