My father is …
One day, during class. The teacher asks the kids:
Teacher: “What is your father doing for a living?”
John: “He’s the garbage man!”, answered the boy
Teacher: “No, John. We don’t say garbage man, we say he works in the Salubrity system. Peter, what’s your father’s job?”
Peter: “My daddy is a grave digger“, said proudly the little boy.
Teacher: “No, no Peter! It’s called a Mortician. Jesse, what does your father do for a living?”
Jesse: “My daddy is a DJ at the Mystic Club.”
Teacher: “What does that mean?”
Jesse: “He’s a ringer in the church choir!”
Thanks Annie for the joke
