[Frasier and Niles wonder why Martin invited them to Duke's Bar]
Daphne: Could it be that he just wants to lift a pint with his sons?
Niles: No. Duke's is where dad hangs out with his cop buddies. It's where he goes to escape the stresses, strains, and petty annoyances of everyday life.
Frasier: In other words, us.
Daphne: If you ask me, you Americans have an unhealthy obsession with sex.
Martin: Hey, I'm sorry we can't all be as chaste and restrained as the Royal Family!
Frasier: Good one, Dad!
Martin: I've been saving it!
Frasier: [seeing Daphne with her clothes in disarray] Apparently, in England, it's the fourth date.
Frasier: What say we go celebrate with a nice dinner at an exclusive boite?
Niles: Yes, but the question remains, what boite?
Niles: Too noisy.
Niles: Too bright.
Niles: Too crowded.
Frasier: We've run out of boites.
Niles: A city this size and only three boites.
Frasier: How do we live?
Daphne: Excuse me? What kind of randy custom is that? First date, second date, whoops, let's all pitch our knickers? The third date might mean that to you Americans, but it takes more than three dates to get bangers and mash with Daphne Moon.
Daphne: I have never met a family that worked so hard at being uncomfortable with each other!
