Okay, you've convinced me, I think the illuminati put this detail there. And yes indeed, I'm still discovering new things in the film. Like most films by the Coen brothers, it's a religious one. The Dude's fatal flaw is that he's unemployed and stagnant, that's why a minor loss (namely his rug) causes him so much pain and he's hurdled into such a crazy episode. God is present in this film, and he's disappointed in the Dude. It should really be seen in comparison with A Serious Man, with which it partially shares a soundtrack.
