There are 3 nuns and a mother superior. The mother superior tells the 3 nuns before you are can receive your saint name and b-day you have one final test. She told them to go commit one sin so that they would not want have urges to be bad.

After the 3 nuns return the mother superior says did you commit your sins. They all shake their heads yes. The first 2 nuns are crying, the 3rd is giggling.

The mother superior says to the first one what sin did you commit child?
The first nun answers w/ tears in her eyes... I was just rotten, I picked flowers from someone's garden.
The mother superior says... Go drink the holy water and it will be alright.
The 3rd nun is dancing around in laughter.

The mother superior asks the 2nd one...
Her whole body is shaking and she is crying. I stold candy from a baby!!!
The mother superior says... My child drink the holy water and you are forgiven.
The 3rd nun falls on the floor hysterically laughing.

The mother superior is disgusted and asks what are you laughing at????
The 3rd nun is barely able to answer through her tears of laughter....
I peed in the Holy water!!!
