The father walks into the church and sees 4 sisters...

He asks what they are waiting for and they say they are there to confess their sins. The father tells them to come one by one, so the first one approaches and says:

"Father, forgive me for my sin. I touched a male's genitals using my left hand."

So the father thinks and says:

"Go there and wash your left hand with the holy water."

And the sister goes and washes her left hand with the holy water.

The second one approaches and says:

"Father, forgive me for my sin. I touched a male's genitals using my left hand and I rubbed it a little bit."

So the father thinks and says:

"Go there and wash your hand with the holy water. Don't forget to rub your hand in the water too."

And the sister goes and washes and rubs her left hand with the holy water.

Then, he realizes that the 3rd and 4th sisters are arguing. Father asks what is going on.

The third one tells the father that the fourth sister is trying to take her spot. The fourth one desperately goes:

"Father, I just wanted to gargle before she washes her ass."
