A middle-aged couple's career and marriage are overturned when a disarming young couple enters their lives.

Josh: For the first time in my life I've stopped thinking of myself as a child imitating an adult.
Cornelia: You feel that way too?
Josh: It's like... he once saw a sincere person and he's been imitating him ever since.
Dr. Nagato: You have arthritis in your knee.
Josh: Arthritis arthritis?
Dr. Nagato: Yes. I usually just say it once.
Fletcher: Before you have a kid, everyone tells you, "It's the best thing you'll ever do." And as soon as you get the baby back from the hospital, those same people are like, "Don't worry, it gets better."
Jamie: I really loved your film. That scene with the dogs around the garbage. How did you stage that?
Josh: I said 'Hey, shoot those dogs'.
Josh: I like our life as it is.
Cornelia: Yeah. I mean if we wanted to take off to Paris tomorrow we could.
Josh: If we're gonna do it, we should plan it with at least a month in advance.
Cornelia: A month is still in the realm of spontaneity.
Cornelia: I wish you'd look at me the way you look at Jamie and Darby. When we first met, you wooed me with romantic e-mails.
Josh: It wouldn't make sense for me to send you e-mails now that we're in the same room all the time.
Cornelia: It's like their apartment is full of everything we once threw out, but it looks so good the way they have it.
Josh: Let's have kids.
Cornelia: I don't want this to be 'Every time you take a hallucinogen you want to have a baby'.
Josh: Not every time.
Cornelia: My dad likes saying, "The more, the more."
Josh: That's because your dad has everything and then he gets more.
Josh: He's not evil, he's just... young.
Josh: I've learned along the way you can discover more by allowing yourself to be surprised by what you encounter.
Cornelia: They made a house out of twigs. And the wolf came.
Josh: He blows it down.
Cornelia: Yeah, but what happens in the middle?
Josh: I keep wanting to do 'This little piggy went to the market, but that's with the toes'.
Josh: It's all a pose. It's like he once saw a sincere person and he's been imitating him ever since.
Fletcher: You're an old man with a hat.
Cornelia: Josh, you know the world isn't a giant conspiracy against you.
Leslie Breitbart: Josh, your sleeve is on fire!
[Jamie puts it out]
Leslie Breitbart: Are you okay, son?
Cornelia: We've got this Ayahuasca ceremony this weekend with Jamie and Darby.
Marina: What's an Ayahuasca ceremony?
Cornelia: You drink this sludgy liquid and you hallucinate and vomit up your demons.
Marina: Okay. Well, we're just having a cookout and maybe playing charades.
