Divine Intervention
four nuns are in a car and as they drive off from the convent, it runs out of petrol.
Nearby is a petrol station, so the nuns walk back to
the convent to get something to carry some petrol in.
They couldn't find any suitable containers so they grabbed some bed bottles.
They go to the petrol station and fill the bed bottles with petrol and take them back to the car.
As they get back to the car there's two drunks standing on the footpath.
Upon watching the nuns emptying the bed bottles into the petrol tank.
one drunk says to the other
"I that works I'm changing my religion"
