Little Johnny came home after school:
"Daddy, I have a bad grade in English language."
"Why?" asked his father.
"Well, the teacher asked us the following question: "Mary entered the forest with John and came out of the forest with Mike. What is Mary?""
"How come what Mary is? A whore, of course," said the father.
"That’s what I said, but the teacher answered Mary was a subject."

    Little Mary came back home after school and said,
"Mommy, today during the school break Johnny kissed me on my lips!"
The mother asked indignantly but in surprise,
"And how did this happen?"
"It was not easy, but three of my classmates helped me to hold him firm."

    Johnny comes back home from school and tells his father, “Dad, tomorrow you are invited to a special parent meetings at school."
“How much special?”
“Well, just me, you, the director and two investigators from the FBI."
