Note that I said really smart*. Did you, for example, consider the possibility that this might actually be the ad? I hear a lot of large companies are going viral nowadays...

As for amount of hits, you don't need to assume. See the related videos for the clip. (there's one with 1 352 154 views currently)

*) No offence meant by this, I just think that creating content for ad revenue in the Internet is not such a new trick anymore.
