I remember when my wife was in labor and the nurse said it was time to push. She gave it everything she had, until a giant fаrт rang out that shook the room.
“Don’t worry,” I said, patting her head. “I’ve heard this kind of thing is perfectly natural during birth. Isn’t that right, nurse?”
“Yes,” said the nurse, gagging, “but it’s usually the mother, not the father.”
