Between Father & Son

Father to son after the exam:  Let me see your report card.
Son : My friend just borrowed it. He wants to scare his father.

A boy come home from school with his exam results
"What did you get ?"  asked his father.
"My marks are under water," said the boy.
"What do you mean 'under water'"
"They are all below 'C' level"

Dad : Son, how can you call your aunt stupid? Go and say
          sorry to her
Son (goes over to the aunt): Aunt, I am sorry you are stupid
