A Brief Conversation

 EXT. DAY. Cold, overcast.

A HUSBAND and WIFE are out for a walk. They have obviously been walking for some time, and conversation has been wandering.

HUSBAND
One day, I should like to own a hybrid car

WIFE
Indeed

HUSBAND
It'd be all good for the environment-y. And we could have a garden, and grow our own petrol

WIFE
Mmm, and ducks could come and visit our petrol pond

HUSBAND
Cute little ducklings, all covered in petrol…

I think that we may have crossed the line of taste

WIFE
No, crossing the line of taste would be actually talking about the ducks being set on fire

HUSBAND
Ah, so this leaves the setting on fire implied in the audience's mind, so they can feel guilty about having bad thoughts later. "They were just cute little ducklings, and I thought about setting them on fire!"

WIFE
Exactly, and then they'll have to go and see a therapist, and talk about their evil, twisted minds. Everything I do is aimed at getting more people into therapy
