A nun was walking in the convent when one of the
priests noticed she was putting on a few pounds.
“Gaining a little weight are we sister Susan?” he asked.
“No, Father. Just a little gas,” Sister Susan explained.

A month or so later the priest noticed that she was
even larger.
“Gaining some weight are we Sister Susan?” he asked again.

“Oh no, Father. Just a little gas,” she replied again.

A couple of months later the priest noticed Sister
Susan pushing a baby carriage around the convent.
He went up to her, leaned over and looked in the
carriage and said, “Cute little fart.”
