Foster's Home for Imaginary Friends, Season 2

Bloo:
So, do we get our super awesome jet cars now?

Mr. Herriman:
[sarcastically, stretching out his head to Bloo] Oh, yes... they're in the mail.

Bloo:
Yes!

Mac:
Um, Bloo. I think he was being sarcastic.

Bloo:
Oh. But who cares?? We're getting jet cars! Jet cars, dude!

Mac:
No, see, he was just saying that because it isn't true.

Bloo:
So he was lying?

Mac:
No, he was using sarcasm. He said the opposite to make it funny! Ha ha!

Bloo:
That wasn't funny. Knock-knock jokes. Knock-knock jokes are funny.

Mac:
[sarcastically] Yeah. Knock-knock jokes are hilarious.

Bloo:
That's what I'm saying!

Mac:
No, I was being sarcastic.

Bloo:
Stop it!
