The Raccoons, Season 3 (1988)

Cyril:
I've been expecting this kind of unhanded chicanery! In fact, I've had a little quiz prepared just for the occasion. It should prove exactly who you are not!

Pigs:
(in unison) All set sir!

Cyril:
Fasten your seatbelt 'Simon', you're in for a bumpy ride! Only my real brother can answer any of these questions! Fire away!

Pig One:
Um, um, what size boots did you used to wear?

Simon:
Simple. Eight!

Pig Two:
Uh, he's right sir!

Cyril:
He is? Well that's a stupid question! Anyone could have guessed that right. Ask him another one!

Pig Two:
Er, okay... what colour were your old boots?

Pig Three:
No peeking!

Simon:
Green.

Pig One:
Right again sir.

Cyril:
What? A lucky guess. Give him a tough one this time.

Pig One:
Um, okay, um... did these boots have any buckles?

Cyril:
Is that all you're going to ask him? Questions about boots?! Who cares! Didn't you find anything else in that trunk? ANYTHING AT ALL?

Pig One:
All we got were his boots.

Cyril:
And here's three more! (He proceeds to kick the pigs away)
