Three nuns, one sin for each.

A priest walks up to three of his purist nuns telling them "Ladies you have been with me in the monastery for as long as I can remember, and neither of you had committed a single sin, and so I reward you today and give you permission to do one single SIN, of course nothing against the law, when you are done come to me tomorrow and tell me of your doings." the three nuns thought for a moment and went on their way, the morning after when the first nun comes back she tell him about dressing in a reveling manner and making out with a random man, he tells her "its fine, go wash your face in the holy water and go back to your duty's." a few minutes later come another nun "well my child tell me of your doings." and goes on telling him that she ran out and spent the night with the first big bulky handsome man she found having wild sexual intercourse with him all night, a bit shaken from the tale he says "its fine, go wash your face in the holy water and go back to your duty's." an hour later the third and last nun comes when he asks "where have you been its already noon!" she tells him that she overslept because she could not wake up to her alarm clock, "but that's not a what he had in mind, that's simply being lazy and irresponsible!" she then looks at him "right sir, the thing is I stayed up all night thinking about a sin I would go about, but nothing really came up to my mind so before going to bed I took a piss in the holy water!."
