Whopper Acquisition Corp AKA Google Inc

Google just filed it's $3.1B merger/acquistion plan for DoubleClick with the SEC. Why I started reading it I have no idea. Found the link on resourceshelf.

What is really funny is that Google has a holding company it uses to do acquisitions called "Whopper Acquisition Corp." Whopper? Anyone know why they structure it this way? I haven't ever heard of Google using holding corps for other big transactions like YouTube. And what a name...
