Phil: I am really sorry. About the cold coffee.
Mitchell: It's not that cold. It's lukewarm, so...
Phil: Funny story about that expression. When the kids were younger, um, we had a, uh, a wading pool-
Mitchell: Uh-huh.
Phil: And occasionally, Luke would have an accident, and, um, Alex would scream, and we'd say, um, "It's okay, honey, he's just making it lukewarm."
