Animaniacs, Season 1

Wakko:
Hey, you wanna hear a joke?

Dr. Scratchansniff:
No! I don't like ze jokes, Wakko!

Wakko:
Not even a knock-knock joke?

Dr. Scratchansniff:
NO!

[Wakko and Dr. Scratchansniff sit quietly for a moment]

Wakko:
It's really funny.

Dr. Scratchansniff:
Oh, alright, fine. One joke.

Wakko:
Knock-knock!

Dr. Scratchansniff:
Who's there?

Wakko:
Max!

Dr. Scratchansniff:
Max, who?

Wakko:
Max wants to come in and go crazy!

Dr. Scratchansniff:
[looks at the audience, confused, then back at Wakko] Well. Okay, now that's not really a joke, is it? You see, because it makes no sense.

Wakko:
It does if you know Max.

Dr. Scratchansniff:
But I don't KNOW Max!

Wakko:
If you did, you'd be laughin'!
