How Do You Make a Video Go Viral?

In order to make a video go viral you need to move two or more emotions, have spectacle and a little bit of story or you could just put a sexy female super model like Heidi Klum dancing around half naked playing Guitar Hero in her underwear.

Like in this video for the Guitar Hero World Tour. It's the Heidi Klum Director's Cut, Directed by Brett Ratner.

It's also a good idea to have a video preview thumbnail with a pretty woman in her bra as well. ;)
