Propaganda in Advertising/PR

Firstly, this ad uses the "beautiful people" technique. What in the world does Paris Hilton have to do with Carl's Jr.? By watching this, I guess people will associate "sexy lady" with "cheeseburger" in their primitive brains and go straight to Carl's Jr. in the hopes that Paris herself will be there, slithering around on the floor and pretending to eat a burger that's bigger than she is.

I also think that "intentional vagueness" is used, simply because this ad doesn't explain anything.
Does the burger taste good? Who knows. Is it a good deal? Probably not. People will draw their own interpretations, such as "Paris Hilton seems to . . . really . . . really . . . like it, so it must be good!" or "Mmm, there's nothing like eating a soapy soggy burger off the dirty wet floor! Let's to to Carl's!"
