Two nuns walk into a liqueur store and ask the man at the counter for a bottle of Blackberry Brandy. The clerk tells the nuns that he knows they are not suppose to drink alcohol and he cannot sell them the bottle.

One of the nuns said Its okay. Its for the Mother Superior. You see, shes constipated. So the clerk sells them the brandy.

After locking up the store at closing time, the clerk walks down the street and sees the two nuns are falling down drunk.

The clerk says Sisters, you lied to me. You said that was for Mother Superiors constipation.

The nun replies It is. When she see us, shes going to SHIT.
