Why didn't he just wash the rug?

Rating: 5/10 (28 December 2014)

This story circulates around a bum like perpetual hippie apparently living on some kind of assets as the story makes a point of him being out of work. He's a lazy, viscously phlegmatic and self centered persona.
Some "hired help" enters his home and almost flushes his head down the WC. The reason for this is not clear but obviously they mistook him for a different guy with the same name, The 'Big' Lebowski, who's enormously well off and sits in a wheel-chair. Some kind of revenge or threat. Anyhow, they pee on the hippie namesake's oriental rug. And thus the story starts rolling.
Now, if you know anything about rugs you'd know that you can actually wash off pee. It's done regularly in Iran where almost every home is furnished up the walls in hand manufactured rugs and carpets, and where young kids might pee, or worse, on them.
This picture, on the other hand, is not washable. After seeing it a dozen of times, I still don't get what it's all about.
The story is too blurry and unintelligible to summarize.
It's entertaining, though, and the soundtrack is great.
I get the feeling that the Coen Bros really wanted to impress Tarantino, as TBL could well have been a comic book story, just like Pulp Fiction.
