Its almost too easy to make fun of Jamba Juice, what with the overpriced drinks, allegedly ripped-off ad campaign, and--no, this isnt a joke--recently launched clothing line, featuring neon-green hoodies emblazoned with the phrase "official taste taster." That said, its truly refreshing (ha) to see the smoothie titan finally start dishing it out. Earlier this month, McDonalds made a play for Jambas market share by launching a line of "real fruit" smoothies. (Theyre actually made from purees.) Rightfully rattled, the San Francisco-based company has responded by launching a new drink called the Cheeseburger Chill, described in a press release as "beefy, smothered in cheese, loaded with your favorite condiments and blended to creamy perfection." Theres even a commercial to whet our appetites:[youtube W_oLzOBgIRU]>We know what youre thinking: This sounds insane. And thats the whole point. The stunt is a fake-out, engineered to suggest that a burger joint getting into the smoothie business is just as ridiculous as a smoothie joint blending up cheeseburgers. Coming from Jamba Juice, the logic is dubious. This is, after all, the same company thats trying to broaden its business by selling pint-sized pizzas and oatmeal, which is no less far-fetched than McDonalds dabbling in smoothies.But well give credit where credit is due. The spoof-commercial is pretty funny, and offering viewers a 1 off Jamba Juice coupon for having to endure a full minute of "stomach clenching video" is a nice touch. Plus, weve heard those McDonalds smoothies are kind of nasty.
