Roz: Happy anniversary!
Frasier: Oh, Roz. Roz. Oh, this is so much fun, Roz. I got you one, too.
Roz: Oh, thank you. Okay, you first. I mean, it's nothing really, it's not expensive or anything, you probably won't even like it. I'm not good at gifts—
Frasier: Look, don't oversell it, Roz. ... It's a tape. "The Dr. Frasier Crane Show: Show #1, May 21st, 1993."
Roz: It's our first broadcast.
Frasier: Oh, Roz, I can't wait to listen to it. Oh, God. Did you ever think I'd stay on the air this long?
Roz: Oh, hell no. [reading the card Frasier got her:] "To Roz, who believed in me from the start."
Frasier: Yes, it's from Hallmark's "Irony" section.
