Quote from Ray in Pilot
Debra: But do they have to bring your brother over? Ray: My brother lives with them. He doesn't like staying alone. Debra: He's 40, Ray. Ray: Come on. He loves the kids. Debra: It's just like... The way Robert eats, you know? The way he has to touch every bite to his chin before he puts it in his mouth. That's weird. Ray: What? That's an idiosyncrasy. It's like when he's counting and he gets to 12, he has to take his shoes off. Everybody has those. Debra: How did he ever become a police sergeant? Ray: Because he's a good cop. And they didn't make him count. Or eat.
