On the way back, they were a few miles from home when they ran out of gas. They were standing beside their car when a truck approached.
Seeing ladies of the cloth in distress, the driver stopped to offer his help. The nuns explained they needed some gas.
The driver of the truck said he would gladly drain some from his tank, but he didnt have a bucket or can.
One of the nuns dug out a clean bedpan and asked the driver if he could use it. He said yes, and proceeded to drain a couple of quarts of gas into the pan.
He waved goodbye to the nuns and left. The nuns were carefully pouring the precious fluid into their gas tank when the highway patrol came by.
The trooper stopped and watched for a minute, then he said: “Sisters, I don’t think it will work, but I sure do admire your faith!”
