Honda, you had me at ninjas. On the heels of Toyota's Swagger Wagon and Kia's rapping hamsters, Honda has created its own time-wasting video snippets meant to show off the roominess and cheekiness of its Jazz model. Made in Australia, the videos present a new twist on how many clowns can fit in a car, or how many non-claustrophobic folks can squeeze into a phone booth. The campaign stuffs ninjas (right), hipsters, rappers and bodybuilders into a Jazz. The ninjas fold themselves into the compact car so quickly, you might miss it if you blink. It's no mean feat for marketers to create spots that go viral—even though they may describe their campaigns as such before a single person passes a link along—but this one seems to be catching on. So far, they've been played more than 400,000 times, with the hipster spot by far the most popular. Bet they couldn't get a pirate in their trunk. Go ninjas!
