Guinea pigs, consummate advertising pros

As advertising characters and/or props, guinea pigs almost never disappoint. And they prove their worth yet again in this Argentine spot by agency El Cielo for cell-phone company Claro. The ad amusingly shows how, for kids these days, getting their first cell phone is often a bigger deal than getting their first pet. That's some great acting on the part of the varmints, one of which is awesome at vibrating. And yet, this is only our second-favorite guinea-pig commercial. The best one is still G4's Midnight Spank spot with the kidney-eating rodent.
