DuckTales, Season 1

Launchpad:
You guys gotta think positive!

Huey:
But, Launchpad, Webby's lost, Unca Scrooge is lost, we're lost...

Louie:
...and there's a monster in these caves trying to get 'em.

Launchpad:
C'mon! There must be something positive about all this.

Dewey:
If we don't keep moving, we're going to freeze to death.

Launchpad:
There you go!... You gotta keep a stiff upper lip, Louie.

Louie:
That's easy. It's frozen.
