So a bus full of nuns die

So sorry if a repost, I'm new at this.

So a bus full of nuns die and they are greeted by St. Peter at the pearly gates. St Peter announces
"If anyone has touched a penis please step forward, dip your hands in the Holy water and then you may enter heaven.
So the first sister steps forward and dips her right hand in the water and then is allowed to pass through
The next nun approaches and dips both hands in and is allowed to enter heaven.
Then suddenly from the back a sister comes running and
St Peter exclaims "Sister Mary there's plenty of time what's the hurry?"
To which Sister Mary replies "Hey if I have to gargle this shit I'm doing it before Sister Patrick sticks her ass in there!"
