N 2: Joke about idiots
Son: Dad, what is an idiot?
Dad: An idiot is a person who tries to explain his ideas in such a strange and long way that another person who is listening to him can't understand him. Do you understand me?
Son: No. N 1: Joke about school and idiots

"Now then mister, why do you consider yourself an idiot?" enquired the teacher with a sneer.
"Well, actually I don't," said the student, "but I hate to see you standing up there all by yourself."
