Keyboard Cat, Snoop, Psy, the Winklevoss twins and Snooki were all in on the joke. Can the same be said for Dennis Rodman and the Prancercise lady? Oh sure, it's just the Wonderful Pistachios campaign revving up another round of zeitgeist-tapping absurdity. There's no apparent end to the reality-TV, pop-culture, animated and sports figures who will make themselves available for these ads. In fact, if this marketer doesn't ask how or why you do it—eat pistachios, that is—then you must not be very important. Rodman? He does it "because he's nuts," says the newest spot, in which the former NBA player turned diplomat appears with a less doughy version of Kim Jong-un (a look-alike) to hawk the healthy snack. And the Prancercise lady? Who can get enough of her spindly, energetic dancing? Next, somebody will have to twerk.
