Frasier: Thanks again for dinner the other night with Maris. You two seem very happy.
Niles: Oh yes, it's love. Like the Arctic Puffin, we've mated for life. Honestly, I can't imagine even looking at another woman.
[As Niles gets up to grab a napkin from another table, Daphne comes to Frasier's table to ask for sugar]
Daphne: Excuse me, sir, have you finished with that sugar?
Frasier: Oh, yes.
[Niles returns to their table without seeing Daphne, but he takes a minute to sniff the air.]
