Petrol?
Sister Mary Ann, who worked for a home health agency, was out making her rounds visiting housebound patients when she ran out of petrol. As luck would have it, a Servo was just a block away. She walked to the station to borrow a can and buy some petrol. The attendant told her that the only can he owned had been loaned out, but she could wait until it was returned.
Since Sister Mary Ann was on the way to see a patient, she decided not to wait and walked back to her car. She looked for something in her car that she could fill with petrol and spotted the bedpan. Always resourceful, Sister Mary Ann carried the bedpan to the station, filled it up, and carried the full bedpan back to her car.
As she was pouring the petrol into her tank, two Baptists watched from across the street.. One of them turned to the
other and said, 'If it starts, I'm turning Catholic.'!!
