Quote from Frank in Debra's Sick
Ray: Okay, I'm back with all the right children. Debra: How are the kids? Ally: Daddy said we could watch TV until we get better. Ray: Dr. Hammond said they'll be fine in about 24 hours. And he was amazed at how identical these twins are. [Marie and Debra laugh] You know, if they ever need x-rays, I bet we only have to bring in one. It was an honest mistake. Robert: Yeah, like father knows best. Frank: He brought the wrong kid. Ray: I know. I now. Frank: Well, I never mixed up you and Robert. Robert: Yes, you did, Dad. Frank: Oh, right.
