The Muppet Show1976

Charlie McCarthy:
Bergen, call the janitor. There's a toad loose in the theater.

Edgar Bergen:
Charlie, Kermit is supposed to be here.

Charlie McCarthy:
Yeah?

Edgar Bergen:
Yes. And besides, don't you know the difference between a frog and a toad?

Charlie McCarthy:
No, I guess not.

Kermit the Frog:
Well, you see, frogs are handsome, debonair and charming, while toads are ugly and give you warts.

Charlie McCarthy:
I see. I guess that means the toad is supposed to be here.
