Quote from Carla in Coach Returns to Action
Sam: [on the phone] Sure, Sister, that'll be fine. You're welcome. [hangs up] Cliff: Hey, Sammy, I didn't know you had a sister. Sam: Oh, no. That's Sister Theresa from St. Matthias School for Girls. She's sending a student over with a playbill. Carla: Hey, you know that St. Matthias is a good school. I've had two kids thrown out of there.
