Swimming

The very naive young nun was assigned to a parish in the country. On the first Saturday, the priest asked her if she wanted to go swimming. She'd never been before, but the priest promised he'd give her lessons. They changed into bathing suits, then the priest offered her a hand while they waded into the water.

They splashed around for a few minutes until the nun turned to the priest and asked, "Father, will I really sink if you take your fingers out of my hole?"
