The three Nuns tell the abbess that they do not want to be nuns anymore. The abbess is a little disappointed, but allows their decision to go ahead. “Alright,” she begins, “If you don’t want to be nuns anymore… Go out and commit a crime, come back afterwards, and drink from the holy water. After that, you will no longer be a nun.”
The three Nuns leave and commit their crimes. The first nun comes back and says to the abbess: “Mother, I stole money from a baker.” The abbess says in return, “Shame on you. Go drink from the holy water and you will not be a nun anymore.” So the first nun does.
The second nun comes back and says “Mother, I murdered a child.” The abbess says, “Good heavens! Go drink from the holy water and you will not be a nun anymore.” So the second nun does.
The third nun comes back, but she is laughing. The abbess is confused, and asks why she is laughing. “Mother,” the third nun says, “I think I’ve done something worse– I pissed in the holy water.”
(Not my joke but I hope it made you smile :))
