Quote from Francis
Lois: [on the phone] No, Francis, everything turned out fine. We agreed not to sue them, and they agreed not to throw Reese in jail. Enough about that. Tell me about your new job.
Francis: Oh, it's great. I've learned so much already. Say, while you were at the zoo, you didn't happen to see any animals giving birth, did you?
Lois: No. Why?
Francis: Just curious. Never mind. [groans] Almost there, sweetie. Just one more push. [cow groans]
