Four nuns have just passed their Theology degrees, they are introduced to the mother superior of the convent they will be staying in. They are told to all meet at the swimming pool for their final assignment. They all duly meet with the mother superior and are told that the swimming pool is filled with holy water, and that what they have done before this day is all forgotten and the parts of their body that have been touched by men/women in a romantic fashion have to be bathed and so cleansed. The first lady stoops down and dips her hand into the water explaining that her boyfriend had held hands with her, the second lady dips her hand into the water and washes her thighs, explaining that her boyfriend had touched her thighs accidentally, the third lady takes off her clothes and dives into the pool and starts swimming, with that the fourth lady runs alongside her and shouts Don't piss in that water, I've got to gargle in it!!!!!
