A bus-load of nuns is killed. They arrive at Heaven's Gate. St. Peter says to the first nun (sister Betty), "I only have one question." Have you ever touched a man's penis?
Sister Betty says. "Well I must admit, I did touch a penis once with my finger." St Peter says. "Dip your finger in this Holy water and you may pass." She does this and passes through.
Next is Sister Katherine. "I will ask you the same." Have you ever touched a man's penis?" She says "Yes I did touch a penis with my bare hand once." St Peter says, "Then dip your hand in this Holy water and you may pass through the gates." She does this and walls through.
All of the suuden there is some rustling going on from the back of the line. Sister Theresa comes bursting up to the front of the line in a panic. St. Peter says "Sister Theresa, what are you doing?"
She says, "If I am going to have to gargle that stuff, I wanted to do it before sister Mary sticks her a.ss in it."
