Have you seen the commercial advertising Hardees' new Thickburger? It looks like this:
The commercial then asks the viewer if she thinks she can do a better job making Thickburger's next commercial and directs her to the web site. However, instead of letting the viewer actually create a true commercial for it and upload it, Hardees gives the user a space for a word or two of text and prefilled music selections. You change their existing commercial with "your" choices. Given a set amount of materials to work with, to me, this sounds more like "Have it your way" with our ingredients commercial.
