Quote from Ray in Pilot
Debra: Look at our boys. Pretty cute, huh? Ray: Yeah, they are. But, you know, I hope they stay cute. Debra: What? Ray: Well, see, I've been thinking, that's the danger of identical twins. They're cute now because they're babies, but when they become adults even if they're slightly ugly, that's gonna be magnified. 'Cause, you know, think,i if you see one slightly ugly man walk across the room, that's no big deal. If you see the same ugliness right behind him... Yeah, that you're gonna notice. You're gonna go: "Hey, I didn't think he was that ugly until I saw it again."
