Quote from Jay in When a Tree Falls
Jay: So he's out in our yard and he's got a boombox. What's the name of that movie with the boombox? Jerry: Oh, "Say Anything." Jay: With John Mahoney. So anyway, he's out there, and he's begging Claire for forgiveness. She's still mad at him. She won't have any of it. So he turns it up full-blast, and it's Olivia Newton-John. And he starts singing, "Let's get Phil-sical"! [all laugh] Phil: It was an inside joke.
