Here is the inevitable ad starring a baby doing Gangnam Style. The product, perhaps less predictable, is E-Lites, an electronic cigarette. It's a pretty macabre conceit. Don't miss your kid's first steps—or in this case, his first imitation of a Korean rapper's dance moves—while you're out literally killing yourself with a smoke. (Reading between the lines, you'll miss a lot more when you're dead, too.) Still, the infant's wobbly take on the horse dance, and the family's slack-jawed reactions, are more or less perfect.
