There were three nuns living in a nunnery, and one friday the head allowed them to have the weekend off to do whatever they pleased.

On the sunday evening the nuns returned and each in turn visited the head nun.

"What sins have you committed?" the head inquired to the first nun.
"I had a night of hard sex with two different men on both friday and saturday."
"Wash your hands and face in the holy water, and your sins will be forgiven by the lord." This the nun did.

Next came the second nun.
"What sins have you committed?" the head asked again.
"I got completely hammered on friday and had sex with a woman on saturday!"
"wash yourself in the holy water and your sins will be forgiven." The nun obayed.

After a delay, the third and final nun entered. the head asked the same question she had asked the other two this nun
to which the nun replied through uncontrollable laughter,
"i pissed in the holy water!!"
