A reminder: you cannot actually *stage* “viral videos.”

The closest that you can come to doing that is to hand a bunch of people video cameras and HOPE that enough of those cameras are turned on and pointed in roughly the right direction when Something Interesting happens.  If you try to force the magic into happening, it won’t.  And then you’ll look like a goofball for trying.

Of course, the outright failures aren’t nearly as entertaining as the we-didn’t-make-any-major-mistakes-so-why-didn’t-it-work? ones.
