Mel: "It's a tough old diner... It's been through a lot."

(Last lines of the series.)
Mel: "Why can't anybody think of some happy things?"
Vera: ""Yeah, let's think about the happy things."
Alice: "Okay."

Alice

"Tommy longs for male companionship."

"When donkeys fly."

~Florence Jean Castleberry

Vera

"Wait a minute. I don't know how to drive."

Mel Sharples : You stow it!

Flo

"When donkeys fly."

Mel Sharples : You stow it!

Another phrase Mel used was during the Jolene era when he frequently said to her "Bag it blondie!"

“So far this week I've been offered candy bars and nylons. What is this, World War 2?”

Mel & Flo:

Mel Sharples : Flo, pick up!

Loved when Mel visited Flo in Texas, and he yelled "Pick-up" from behind the bar and Flo reacted like she was back at the diner.

Alice Hyatt: Yes, why I won't go out to dinner with you. A. I am a widow I have a good 10 years on you I'm old enough to be your grand... baby sitter. B. I am a baby sitter for my own 12 year old son. C. My last date turned out to have a wife who looked to be about 19 months pregnant. D. I am a singer and I'm saving my nighttime energy to get another singing job. E...

Mel: "Sex education? Hell, I could teach that."

Vera: "Remember, he who lives by the spatula, shall die by the spatula."

Tommy: "I'll sure be glad when I'm old enought to end the discussion."

Mel: "That's like a day without sunshine!"

Vera: "That's life, Mel. Sometimes a doughnut flies by."

Belle: "We like to think of him as 'pleasingly plump'."

Vera: "Thanks. I was getting waitress elbow."

Principal Solomon: ""There's a riot in the human behavior class."

Mel: "Like father, like son."
Secretary: "I certainly hope not."

Vera: Oh, I have wild dreams, too. Last night, I dreamed I was eating spaghetti, and when I woke up, my pajama strings were missing!
Flo [flatly]: Good, Vera.
