Gas??

A priest was talking to a nun, and he saw that her belly was getting
bigger, and he made a comment about it. She replied to
him that it wasjust a little gas.

A couple months later, he ran into her again. This
time, her belly was really big. She just patted her
belly and said, "Just a little gas."

Two months went by, and he came across the nun again,
and she was pushing a baby carriage.
The priest bent down and looked into
the carriage and said,
"Cute little fart, isn't he?"
