Exercise with us or die of DVT!

This video just came in from a reader (Thank you meckleychina!). Apparently the Shanghai-based budget airline Spring Airlines now makes its passengers do in flight exercises. From what we see in the video at least, everyone is taking it very seriously. Now nobody wants to be one of the unlucky few to die of deep-vein thrombosis(DVT) in the air, right? Smaller Chinese boutique airlines have been trying ways and means of injecting more "fun“ into the flying experience lately. Shanghaiist has been flying Hainan Airlines (which is partly owned by George Soros by the way) a lot more recently, and they typically have a little auction game where tickets are given away at below rack rates. Erm still not quite our idea of fun, but you have to give them marks for trying. Does anyone else have interesting experiences with other airlines to share?
