A nun wakes up and starts walking through the convent.
The first nun she meets says, You got out of the wrong side of the bed this morning.
She shakes it off and keeps walking.
Then the second nun says the same thing You got out of the wrong side of the bed this morning.
Now shes a bit annoyed... but keeps walking.
She hears the same comment from three more nuns. Now she's fuming! 
She storms straight to the Mother Superiors office.
Before the Mother Superior can say a word, the nun snaps:
DONT TELL ME I GOT OUT OF THE WRONG SIDE OF THE BED THIS MORNING!
The Mother Superior calmly replies,
I wasnt going to say that at all. I was just going to ask...
why are you wearing the Bishops slippers?
