Here's one way to prevent obesity: Take a cue from the teen-aged Korean girls in this odd Pizza Hut commercial making its way round the Internet and have a dance party whilst chowing down on a slice:
In the ad, five girls break into a choreographed dance routine after being served a pizza (which, by the way, looks infinitely better than the Pizza Hut pizza I've sampled here at home).
The end of the video features a tutorial in case you're feeling particularly awkward and want to learn the dance moves yourself.
You've got to see it to believe it:
Do you think the Pizza Hut dance will catch on?
