Here's an old favourite of mine....
Little Johnny was sitting in his Prep Grade when the teacher asked each of the students what their fathers did for a living.
Mary answered first, "My daddy is a fire fighter! He puts out fires and saves people every day!"
Next, Billy answered "My dad’s a cop! He has a gun and drives around in a police car with the sirens on!"
Joey who sat next to Billy answered "My dad is a doctor, and everyday he helps sick people."
These common answers all circulated around the room, but Little Johnny would not answer, so the teachers asked him "Johnny, what does your father do?"
Johnny Calmly took a deep breath and said, "My dad works at a bar and takes his clothes off for other men for money, and sometimes if the offer is good enough, he will go to a cheap hotel and sleep with the other man."
The teacher shocked by this, took Johnny aside and asked, "Is that really what your father does!?!"
Johnny replied, "No Miss. My father plays for Parramatta Eels. I was just too embarrassed to tell the truth."
