Quote from Niles in Good Samaritan
Daphne: I must say, I feel a bit bad for Freddie. None of his mates are going to be here, just us three old fogies yelling "Surprise". Martin: Well, any party he's at with you is gonna be a treat for him. You know, he's got that little crush on you. Niles: If you really want Frederick to enjoy himself, he especially likes you in that little blue cocktail dress. Daphne: I'm not sure that dress is appropriate for a child's birthday party. Niles: Well, it's hardly a party, it's just us fogies.
