Viral marketing is kind of like pornography. It's hard to predict what it will look like, but you know it when you see it. This specific piece of viral marketing is even more like porn in that it involves a sloppy makeout scene (and torrid love affair) between comedian Sarah Silverman and a stuffed, serenading Unicorn.
You can thank Juicy Fruit for this gem, the company that somehow associates serenading unicorns with selling gum. Watch the entire relationship unfold in this ridiculous video featuring music by Aerosmith (for some reason).
