Warren Buffett is helping to pitch Dairy Queen just as Kansas City, Mo.-based agency Barkley is airing its first TV ad for the chain, five months after it landed the creative account. The godfather of DQ parent Berkshire Hathaway does not appear in the spot—although a lookalike does pop up in the middle of it. (Buffett has done ads before, as you'll surely recall his cringe-worthy star turn as Axl Rose in this crazy 2010 Geico video.) The DQ voiceover explains, "Here's to our fans. The local heroes … and local legends. The next in line … and the next generation. At DQ, we don't make fast food. We make fan food." Buffett is doing his part beyond the advertising, though. On Monday night, he and DQ CEO John Gainor visited an Omaha, Neb., DQ to test the first S'Mores Blizzard of the summer.
