The Mother Superior of a convent wakes up one morning feeling wonderful. She gets dressed and heads over to have some breakfast. On the way, she encounters Sister Mary. Sister Mary says "Good morning, Mother Superior. Did you sleep on the wrong side of the bed?" The Mother Superior responds "No, I'm feeling very happy this morning." Next, she encounters Sister Rebecca. Sister Rebecca says "Good morning, Mother Superior. Did you wake up on the wrong side of the bed?" The Mother Superior answers "No, I'm feeling quite content and joyful this morning." Then the Mother Superior meets Sister Sarah. Sister Sarah says "Good morning, Mother Superior. Did you wake up on the wrong side of the bed this morning?" By this point, the Mother Superior is wondering if something's wrong. So she tells Sister Sarah "You know, you're the third person this morning who's asked me that. Do I look grumpy?" Sister Sarah answers "No, Mother Superior. You're wearing the bishop's shoes."
