Not since Miami Vice (circa 1984, not 2006) has Phil Collins' greatest solo achievement (no, not "Sussudio," Patrick Bateman fans) inspired such chills. To those who would ask, in critical tones, what's a drumming gorilla got to do with selling a milk chocolate bar, I'd have to ask in return: are you not paying attention? It says right there on the tin: "a glass and a half full of joy." The combination of a gorilla and the iconic drum riff represent more than a regular, expected portion of joy, and so does the chocolate bar. What else is there to understand? Why is a drumming gorilla any less relevant to the way you rationally or emotionally clock a chocolate brand than, oh, lets see, a plump-lipped woman swirling around in diaphanous fabrics? It's chocolate. You know what it looks like. The whole point of chocolate is to alter your brain chemistry, so it makes perfect sense that Fallon, the creators of this video, would offer up sights and sounds (and unusual combinations thereof) that provoke some deeply rooted sensations.
