Two nuns were driving alone out in the

boonies. They ran out of gas.
Fortunately they could walk to a gas
station not far away, where they
asked to purchase a can of
gasoline. “I’m sorry, sister,” said the
attendant, “but all I have for you
to carry it in is an old chamber
pot. The nuns agreed that this
would be fine. They returned to the car.
As they were pouring the
gasoline into the tank, a man drove by,
stopped
his car, and said,
“Oh sister, if only I had your faith.”
