Quote from Frasier in Maris Returns
Peggy: Dr. Crane? I'm back from lunch. Your next patient is here. Frasier: [to Niles & Martin] Thank you, Peggy. Well, I'd love to stay here and chat, but duty calls. Peggy: [whispering to Niles & Martin] If you want to wait, he's usually very quick. Frasier: Thank you, Peggy.
