Three Nuns are in line at the gates to get into Heaven Saint Peter tells them “Before you may enter the gates of Heaven, if you have ever touched a mans penis, place that body part in this bowl of holy water so you may be cleansed.”
The first Nun steps up and places her hand in the water, then walks into Heaven.
The third Nun jumps in front of the second Nun and asks “can I gargle the water before she sticks her butt in it?”
