Struggling retailer Best Buy(BBY) clearly needs some star power, and who better to polish the company's image than show biz darling Amy Poehler? The "Parks and Recreation" star was a hit co-hosting this year's Golden Globes with Tina Fey. In one zinger, Poehler compared the torture depicted in director Kathryn Bigelow's film "Zero Dark Thirty" with her marriage to "Titanic" director James Cameron. In the Best Buy ad, Poehler is obviously playing a customer, but the company is keeping the punch line a secret, for now.
