Although necessary to the plot, it's strange that Frasier and Niles would move Martin's chair a full day before their wine-tasting. What's more, Martin, who has barely agreed to it being moved in the first place, makes no complaint about being inconvenienced for an additional and unnecessary 24 hours.
Comment: In the opening scene, Frasier tells Roz that he is hosting a wine-tasting that night. It's possible that originally everything was meant to happen on the same day, but was later changed because their were too many events to fit into a single afternoon.
(Frasier has just correctly identified a wine in a blindfolded taste test)
Daphne: How is it those same taste buds can't tell the difference between my pot roast and my flank steak.
Frasier: Considering you learned to cook in England it's a wonder I can tell your flank steak from a braised tennis ball.
This is the first time in the series that Daphne's abilities as a cook have been called into question. Until now, she has been presented as being quite capable in the kitchen. Several years later, her lack of culinary skills would become a great source of humor and ultimately, an issue in her relationship with Niles.
Roz: Well, when I'm handing out baloney sandwiches this weekend at the homeless shelter, it will do my heart good to know that a bunch of wealthy men are swishing two-hundred-dollar bottles of wine and spitting it into silver buckets!
Frasier: It's not like we don't recycle the bottles.
(Frasier comes from his bathroom, bits of tissue stuck all over his face)
Martin: Geez! I thought you were just gonna slit your wrists. Looks like you went for death by a thousand cuts.
Frasier: (with slowly building anger) I cut myself because I was shaving without water. And why was there no water? Because I had to move your chair -- which gouged the floor which made me call for Joe who found bad pipes which called for Cecil who ate the cat that killed the rat that lived in the house that Frasier built!
Frasier: It's over! It's over! Sing, fat lady, sing!
Niles: If you had ever smelled her hair, you'd know she was worth at least one more try. She is an angel, and she is a goddess. And she's waiting for you in the bathroom.
Frasier: I don't know what sort of twisted fantasy you've concocted about you and Daphne. I suppose it involves a comet hitting the earth and you and she having to rebuild the species. But trust me, Niles, it's not going to happen. She needs a man--one who can do more for her than just smell her hair.
Frasier: This is not like marriage vows, or a promise to a dying parent. This really, really counts.
