Two priests are off to the showers late one night. They undress and step into the showers before they realize there is no soap. Father Bill says he has soap in his room and goes to get it, not bothering to dress. He grabs two bars of soap, one in each hand and heads back to the showers.
He is halfway down the hall when he sees three nuns heading his way. Having no place to hide, he stands against the wall and freezes like he's a statue. The nuns stop and comment on how lifelike he looks. The first nun cannot resist temptation, suddenly reaches out and pulls on his manhood. Startled, he drops one of the bars of soap. "Oh look" says the first nun, "its a soap dispenser."
To test her theory the second nun also pulls on his manhood. Sure enough, he drops the second bar of soap.
The third nun decides to have a go. She pulls once, then twice and three times but nothing happens. So she gives several more tugs, then yells! "Mary, Mother of God - Hand Lotion too!"
