Foot in the Door

If you've got 60 seconds to watch this video, then I've got a question for you.

I get it, but here's my question: How would you make this happen in a single persuasive text?

If you were only able to compose and deliver one text, how would you use the "foot in the door" technique with a reader, a viewer, or a listener?

It's a pretty common constraint, having one chance to make your case.

So, what would you do?

Or what have you seen others do?
