It was the first day of school.

Harry's mother went into his bedroom and said,

"Come on Harry, get up now. You have to go to school today."

"But I don't want to go to school," replied Harry,

"I want to stay in bed. Why do I have to go to school"?

"Because," answered his mother,
"You're The Teacher!"

Teacher: Will any idiot in the room stand up please?
(a student stands up)

Teacher: Why do you think you are an idiot?

Student: actually I don't,
but I hate to see you standing there all by Yourself.
