A Nun joins a convent that requires a vow of silence. The Nun works for ten years and is called to the office where Mother Superior tells her she can speak two words. The Nun says, "Food cold."
Ten years later, the same thing happens and she says, "Bed hard."
And again ten years later she says, "I quit."
To this last comments, Mother Superior says, Well I'm not surprised, that's all you've done for thirty years is bltch.
