Oh My God-One Day at A Time
Dy-No Mite-Good Times
Stifle yourself will you Edith?-All In The Family

First one that pops in my head:

"I'll bet the neighbors are just lovin' this" by Mama on "Mama's Family"

from the "WKRP In Cincinnati" episode, "Turkeys Away":
At the end of the episode, when a befuddled and weary Mr. Carlson says, "As God is my witness, I thought turkeys could fly."

From All in the Family:

Archie Bunker to Mike - "You are a meathead, dead from the neck up."
