Fighting Nuns

One day there were four nuns in line for confessional.

The first nun said, "Forgive me, father, for I have sinned."

He asked how.

She said "I saw a man's private part." He told her to wash her eyes with holy water.

The second nun comes in and says, "Forgive me, father, for I have sinned."

He asked how.

"I touched a man's private parts." He told her to wash her hands in holy water.

Then he heard the third and fourth nun fighting. He asked why they were fighting.

The fourth nun said, "I'm not going to wash my mouth in the holy water if she is going to sit in it."
