Four nuns die and arrive at the pearly gates. They line up in front of Saint Peter.
"Sisters, welcome to heaven. Before you enter, you must be cleansed of sin in this holy water" he says, pointing at the chalice beside him.
He calls up the first Nun and says "Have you ever touched a man's penis?" "Yes" responds the Nun. "With the tip of my finger".
Saint Peter nods solemnly and has the nun dip her finger into the holy water. She then proceeds into heaven.
He calls up the second Nun and poses the same question. She responds "Yes, with my entire hand".
Saint peter has her plunge her entire hand into the holy water. She is purified, and enters heaven.
He is about to call up the third Nun, when the fourth in line runs forward and interrupts him.
"Let me go next. I'm not gargling that shit after she dips her arse in it!".
