Jack and Molly are sitting in school one day.

Molly is asleep when the teacher asks her a question, "Molly, who created Heaven and Earth?"

Jack sees Molly is sleeping and quickly pokes her with a sharp pencil.

"Jesus Christ almighty!" shouts Molly.

The next day the teacher asks, "Molly, who created Heaven and Earth?"

"Jesus Christ almighty!" she shouts.

"Correct again," says the teacher.

The next day, for a 3rd time, Molly is asleep.
