Monty Python's Flying Circus, Series 1

Pepperpot #1:
I can't tell the difference between Whizzo butter and this dead crab.

Interviewer:
Yes, we find that 9 out of 10 British housewives can't tell the difference between Whizzo Butter and a dead crab.

Various Pepperpots:
It's true… We can't… No.

Pepperpot #2:
Here. Here! You're on television, aren't you?

Interviewer:
[humbly] Yes, yes…

Pepperpot #2:
He does the thing with one of those silly women who can't tell Whizzo Butter from a dead crab.

Various Pepperpots:
Yeah, yeah.

Pepperpot #3:
You try that around here, young man, and we'll slit your face.

Pepperpot #4:
[quietly] Yeah, with a razor.
