The teacher was asking all the kids in the class what their parents did for a living.

Mary got up and said, "My Dad is a pilot, and my Mommy is an architect."

"Great," said the teacher.

Michael got up and said, "My Dad is a Doctor, and my Mom is a housewife."

"Good," said the teacher.

Johnny was last in the class and when he got up he said: "My Mommy, she is a substitute."

Knowing better about his background and always striving to correct the kids, the teacher said, "You mean she is a prostitute."

"No," Said Johnny, "my Sister, she is the prostitute, but when she does not feel well, my Mommy substitutes."
