On Monday, Crispin Porter + Bogusky began holding quick-fire Kraft Macaroni & Cheese contests, in which anyone who tweeted about Mac & Cheese had a chance at getting his or her tweet turned into a commercial. So far, they’ve made three spots—one of which (below) aired on TBS’s Conan and Lopez Tonight last night, with two others (after the jump) getting posted to the brand’s Facebook page. It looks like more Twitter-inspired spots are on the way, with the brand reaching out to people as we speak (and promising a national spot, so the TBS tie-in might be a daily thing for the time being). The brand is really into Twitter lately, having also made the cool Mac & Jinx game. And these new ads are pretty good (if rather non sequitur) for being whipped up in just a few hours. They’ve got decent humor, and the world’s most famous homeless man is still voicing the slogan. Plus, this kind of quick content goes perfectly with the brand. Don’t most people only make Mac & Cheese when they’re lazy and want something fast?
