T. V. Sitcom Trivia

[Dragon Drop]

What very famous sitcom contained the following gag --

Female character: "Do you like this hairdo, dear?"

Male character: "Yeah. It makes you look older."

 

[Dragon Drop]

I guess this is one of those questions where nobody knows the answer, but nobody cares either.

Actually, the two characters speaking there were a small child and his mother. ("Leave It to Beaver")
