Jenny goes to church to confess her sins to the local priest. "Forgive me father for I have sinned."
"Tell me of your sins Jennifer."
"Oh father, last night my boyfriend and I made love seven times in the hay."
The priest ponders this then says: "Take seven lemons, squeeze the juice into a tall glass then drink it."
"Will this cleanse my soul of my sins father?"
"No," the priest says. "But it will wipe that bloody smile off your face."
