To promote yesterday's iTunes release of the pair's new short, We Once Were a Fairytale, Spike Jonze posted this medium-funny behind-the-scenes video of him pretending to slap a distracted Kanye West on the set. Given Kanye's popularity these days, this seems like pretty smart marketing. Also, bear in mind that this clip was shot before Kanye pissed Spike off for real by leaking Fairytale on his blog last week, so it might be the first in a series.
