One of mine and my sister's favorite moments is when Eddie's makes his joke about "the downstairs area," and holds up his hand for a highfive, and they are like "um, no," and then Katherine points to Michael, like "my little kid is right here, dude," but he misinterprets it as "oh, he'd like the joke!" so he leans over so the kid can high five him.
But basically the whole movie. And the scene where they talk about what they love about the other?
