Comic Relief: "Anybody want a peanut?"

I am studying the screenwriting style of William Goldman.  His screenplay for The Princess Bride (1987) is a treasure of humorous scenes and dialogue.  In the following scene, humor comes through incongruity: two supposed "thugs" share the gift of rhyme as a way to sooth the giant's feelings after being insulted.

FEZZIK

…fuss…fuss…

I think he likes to scream at us.

INIGO

FEZZIK

INIGO

(proudly)

VIZZINI

As they sail off, we hear their voices as the boat recedes.

INIGO

FEZZIK

VIZZINI 

No more rhymes now, I mean it.

FEZZIK

Anybody want a peanut?

As Vizzini screams we

DISSOLVE TO

THE SAILBOAT RACING ACROSS THE DARK WATERS.

Here's the scene with their rhyming.
