Frasier: All right! I am moments away from succumbing once and for all to this flu, but I will take one stab at this and then I am going to sink, Hippopotamus-like, beneath the bubbles. I think what this all comes down to is a dispute over turf. Daphne and Sherry are like two animals scent-marking their territory, which in this case is you, Dad.
Martin: You couldn't come up with a less disgusting comparison?
Frasier: All right, all right, fine, it's like the Roman emperor Tiberius, his mother Livia, and his wife Vipsania.
Martin: What?
Sherry: Huh?
Daphne: Who?
Niles: Go on.
