Sam: Great. Why?
Rebecca: Because you'll never get it and I mean that in every sense of the word. It's a song.
Cliff: Some mornings you get up; look yourself in the mirror and ya gotta ask "why me?"
Norm: Cliffie, it's just a hair cut. It'll grow back.
Sam: I've been embarrassed for the last time. I just came onto Rebecca for the I don't know how manyth time.
Sam: Thank you, Carla.

Cliff: This is our story.
Cliff: As they say in the service, here's looking up your address!

Please Mister Postman: A song that has the distinction of having reached #1 twice. In 1961 "Please Mister Postman" was a hit for a group called the Marvelettes; it reached number one again in 1975 as recorded by the Carpenters.
When trying to guess which song made a teenage Rebecca's knees turn to butter, Sam sings snatches of Blue On Blue by Bobby Vinton, Cherish by The Association, and In-A-Gadda-Da-Vida by Iron Butterfly. Frasier suggests Che Gelida Manina from the opera La Boheme by Puccini. Cliff suggests Ballad of the Green Berets by Sgt. Barry Sadler, and Woody sings part of it; later Woody singing it while Sam, Frasier and Norm hum it reminds Cliff of his duty to his country.
