Screwball Squirrel (1944)
Screwy Squirrel: Well, that's the end of him. You people want in on a little secret? You wanna know how I tricked that guy all through the picture?
[a second Screwy Squirrel appears]
Screwy Squirrel: [Both of them] We was twins all the time! Ha ha ha ha!
[Two Meatheads appear, each taking a hold of one of the Screwys]
Meathead: [Both of them] So was we. Ha ha ha ha!
Sammy Squirrel: My cartoon would have been cuter.
[They all beat up Sammy]
Screwy Squirrel: Hello, Meathead?
Meathead: Uh, yeah?
Screwy Squirrel: Do you chase squirrels?
Meathead: Nope, n-nothing but birds, I'm a bird dog, registered, p-pedigreed b-bird dog, I chase nothing but birds, that's all, just birds.
Screwy Squirrel: Aw, you're probably too slow to chase squirrels. You're yellow. Why you... Oh, pardon me.
[Closes phone booth door so that audience cannot hear; blows raspberry through phone; Meathead arrives instantly]
Screwy Squirrel: I knew that'd get him. Ha ha ha ha!
