Martin: I thought you were just going to slit your wrists. Looks like you went for death by a thousand cuts.
Frasier: I cut myself shaving because I was shaving without water. 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!
During the scene where Frasier and Roz are talking at her apartment, the mug that had been sitting on a tray moves off the tray and is sitting right on the table.
"Tossed Salads and Scrambled Eggs", the song played over the ending credits, is performed by Kelsey Grammer.
