Quote from Niles in And the Dish Ran Away with the Spoon (Part 2)
Mel: Niles, this is important. If anyone should ask about the honeymoon, we're flying to Paris, then we're taking the Orient Express to Venice, where we'll spend two weeks at the Mansarda Palazzetto suite at the Cipriani. [Niles stares at her] What's the matter? Niles: Sounds like a wonderful trip. Mel: It's not my fault we're not going. Niles: I know.
