Lanny and Tracy Barnes, Olympic biathletes, are the subjects of what may be the best Olympic advertisement to come out of the 2014 games. And it’s by Guinness. But watch it now, because on January 30th, it disappears. The Olympic committee bans any commercials featuring Olympic athletes for brands that are not official sponsors of the games. Guinness, not an official sponsor. Budweiser, is. (We like both.) Kudos to the copywriter on this one by the way. That ending tag line belongs on a bumper sticker somewhere.
