Freakazoid!, Season 1

Duncan Douglas:
We'd be at grandpa's by now if it weren't for Dexter.

Dexter Douglas:
Hey, I got lost in the desert.

Duncan Douglas:
And you weren't around to help when that blue guy jumped me again.

Mr. Douglas:
You're the only one who see this blue guy, Duncan.

Duncan Douglas:
He's real.

Mrs. Douglas:
Of course, he's real to you, dear. But that's because, you're probably insane.

[Dexter starts laughing. Duncan gets annoyed.]

Duncan Douglas:
What are you laughing at?!
