Walter Sobchak: I'm shomer shabbos. Donny: What's that? The Dude: Yeah, and in the meantime, what do I tell Lebowski? Walter Sobchak: Saturday, Donny, is Shabbos, the Jewish day of rest. That means that I don't work, I don't drive a car, I don't fucking ride in a car, I don't handle money, I don't turn on the oven, and I sure as shit *don't fucking roll*! Donny: Sheesh. Walter Sobchak: Shomer shabbos! The Dude: Walter, how am I going to... Walter Sobchak: Shomer fucking shabbos.
