Cheers, Season 4

[after Andy leaves the bar, Diane follows Sam into the office]

Diane:
Sam, I'm sorry. I feel awful. You were right. Please accept my apology.

Sam:
Oh, forget it, Diane. I forgive you. "The quality of mercy is not strained; it droppeth as the gentle rain from Heaven upon the place beneath. It is twice blest: it blesseth him that gives and him that takes."

Diane:

Sam:
I think you heard me.

Diane:
Yes, but YOU said it.

Sam:
[puts on his smoking jacket; Diane is astounded] Come on, Diane. You really didn't believe that buffoonish façade that I've been perpetrating for the benefit of my blue-collar clientele did you?
