Naked truth about nude Bud Light ad: We get cheap beer

The new Bud Light commercial, introduced online Wednesday, features pudgy, naked male flesh. It is the latest in down-market brewing's glorious history of using nudity to sell beer. Only instead of buxom babes, we get 60 seconds of office drones stripping frantically because the company clothing drive is offering a Bud Light for every item donated.

But is Bud Light stripping scared? And will that benefit Joe Six-Pack at the cash register? Donald Lichtenstein, a marketing professor at the University of Colorado's Leeds School of Business, believes the brand is perhaps acting out in fear of even cheaper beer horning in on its low-brau base.

"I'll bet some part of it is a reaction to the market share Pabst is getting," Lichtenstein told WalletPop.
