Agile, if it can work for millions of users why can't YOU do it?

Agile software development is all about delivering working software that delivers the highest value outcome as fast as possible. Anything that gets in the way of that is to be spurned as you would spurn a rabid dog.

No-one, but no-one, will argue with that.
They may argue with "how" it is performed.

And when they come back with any number of excuses don't let that be the end of it.
If they say anything along the lines of, "Agile only works on small developments with small teams" retort with this from Google's Introducing GMail Labs:

The idea behind Labs is that any engineer can go to lunch, come up with a cool idea, code it up, and ship it as a Labs feature. To tens of millions of users. No design reviews, no product analysis, and to be honest, not that much testing. Some of the Labs features will occasionally break. (There's an escape hatch.)

GMail, small, no!
Google, small, no!
