I never watched more than a few episodes of Frasier, but I remember a commercial for an episode of it - one I unsuccessfully tried to find online just now. I shall paraphrase:

Niles(?): "What perfume is that?"

Unknown woman: "It's 'Obsession.'"

Niles: "No, it's not, I was just curious, really."

I hope you have enjoyed this flawed reenactment.
