A nun was walking in the convent when one of the Fathers
noticed she was gaining
a little weight. “Gaining a little weight are we sister
Susan?”, he asked.

“Oh no, Father. Just a little gas.” Sister Susan explained,
matter-of-factly.

A month or so later the Father 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 few months later the Father noticed Sister Susan
pushing a baby carraige in the convent.

He leaned over and looked in the carraige and said
-
“What a cute little fart!”
