Let's make a video for Barack Obama!
Here's the challenge: take the new will.i.am video in support of Barack Obama, you know, the really creepy one with the chanting and the braindead celebrities like Jessica Alba and others I have no hope of identifying telling us how Obama's going to save the environment and bring world peace just before he brings all of us a pony and a shiny new bicycle. You know, that one.
Then, replace or augment the soundtrack with Hare Krishna chanting (link, link), preferably one that's as absolutely annoying as possible, just chanting "Hare Krishna" over and over and over and over again. For extra points, mix in some sounds of other groups which are considered to be cults (just avoid that one, the you-know-what-I-mean-one, unless you want a snake in your mailbox). Maybe throw in a very light touch of marching (go easy on that, can't overdo it). Maybe reference The Comet with a brief image of black Nikes.
But, you've got to do it in a way that's tasteful. And, make sure you do it all legal like: adding a new soundtrack to the will.i.am video would probably be fair use, but taking good portions of content from one of those Hare Krishna videos would not be.
For extra credit, load the video on a laptop and play it over and over at full volume while asking for donations at your local airport.
