Herr Funk:
You'll never understand me, will you, Schultz?

Schultz:
But you let the bird fly away.

Herr Funk:
Not the bird, Schultz, my Judas goat.

Schultz:
Judas goat?

Herr Funk:
I'll tell you what that is: in the stockyards they have a trained goat that leads the sheep down the runway to the slaughter block. The little goat is unsuspected, but he still betrays the sheep. That is why they call him Judas.
