Parents scheming:

Burt: Okay can we just have a show of hands that we all still think this is a crazy idea? Okay good. That settles it. I'm pulling the plug!
Carole: Burt, calm down.
Burt: Calm down, Carole? Our kids are getting hitched. We screwed up big time. We started playing these crazy reverse psychology games with them.
Hiram: The blame game? This will be fun. Bring it, Burt.
Carole: How did we screw up? What? By raising two, kind, wonderful, independently-minded children?
Hiram: I agree with Burt. They're in love, Wunderbar! But nowhere near ready for this kind of commitment.
Carole: At least we're here. The truth is if we had come down hard on them, they would have gone behind our back and eloped. Trust me. I know my son, okay? And once he puts his mind to something, there is no getting him off of it.
Hiram: Same with Rachel. At this point, even Patti LuPone herself couldn't talk her out of marrying Finn.
Leroy: Barbra could.
Hiram: Maybe Barbra...
Burt: Who's Barbra?
Carole: Streisand.
Hiram: But, since Babs is probably shopping in her private underground mall right now (you know she has her own mall?) Here's what we're gonna do. When the justice of the peace says "Does anybody here object?"
Burt: Yeah, hell yeah! I do!
Hiram: We all say "We do!" with feeeeeeeling. Burt, you will run interference with Finn. Carole, you will distract the Justice of the Peace with your feminine wiles. I will hustle Rachel out the side door and into our waiting car where you, Leroy, will drive (I don't drive) straight to Broadway. And if that doesn't start to get our baby girl back on her career track, I don't know what will. Are we agreed?
Burt: Sounds like a plan.
