It's pure genius and here's why. I was first pissed off that they were crucifying a Phil Collins song, but the huge Gorilla kept me watching. The facial expressions were also classic.

It's also got a hard viral nature to it, that I feel will be sweeping the net shortly. It doesn't have anything to do with Caramilk, but who cares... Absolutely genius!
