Quote from Ross in The One Where Ross Can't Flirt
Ross: Hey, you know that smell gas has? Caitlin: Yeah. Ross: They put that in. Caitlin: What? Ross: The gas is odorless. But they add the smell so you know when there's a leak. Caitlin: Well, okay. Ross: A lot of other gas smells. Chandler: Oh, the humanity. Ross: Methane smells. Caitlin: You know what? Actually, I really should go. Ross: But I haven't paid you yet. Caitlin: You know what, that's okay. You guys have ordered so many that this one's on me. Ross: Was I talking to her about gas? Chandler: More so than anything else. Phoebe: I found it interesting.
