A nun was walking in the convent when one of the priests noticed she was gaining a little. weight.
“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 had gained even more weight.
“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 leaned over and looked in the carriage and said, “Cute little fart.”
