The Muppet Show, Season 4 (1979-1980)

Waldorf:
Statler isn't here tonight, Kermit! He's sick!

Kermit:
Oh, that's too bad. The flu?

Waldorf:
No, the show! He's sick of it! (laughs)

Kermit:
Well, uh, don't get lonely up there, okay?

Waldorf:
Not much chance of that. My wife is using Statler's ticket. She's just powdering her nose.

Kermit:
No kidding. I've always wanted to meet your wife.

[Astoria, a woman who looks exactly like Statler, appears in the box]

Astoria:
I thought the show had started! Who's the frog?

Waldorf:
That's Kermit, dear.

Kermit:
What's your wife's name, Waldorf?

Waldorf:
Astoria!
