At this point it's obvious that the latest Vaughn/Wilson chuckle vehicle was at least loosely organized by Google. It's a marketing video—as if the promise of $20,000 summers weren't enough to seduce intern candidates—and Google isn't even trying to hide it.
If you head to the Google Students page, which offers information for those who want a shot at the twenty grand and a desk at the company someday, you'll see these words:
MEET THE *REAL* SUMMER INTERNS. And right there next to it is a picture of Vaughn and Wilson, mid-joke, with a fat link to a scene from The Internship.
We joked before. The movie is just an ad for Google! That's totally an ad! No, but really, it is an advertisement, on Google.com. A visual advertisement that people will pay to watch in a large room.
