Oh my god

There were three nuns talking and one nun said, "I was cleaning the priest's chamber, and I found some Playboy magazines under his pillow, so I burned them." The nuns looked at each other and the next one said, "That's nothing, I found a box of condoms in his drawer, so I poked little holes in them with a nail." The third nun suddenly jumped out of her seat and said, "Oh my god! I got to go."
