There's a scene at the end of the movie There Will Be Blood where Daniel Plainview, the oil tycoon, is ranting at the minister Eli Sunday. Eli asks Daniel for money in exchange for giving Daniel the right to pump oil from one of his church member's land.
Daniel gives a scary wacked-out explanation of how he has already pumped the oil out from under the land using the analogy of a long straw and the phrase "I Drink Your Milkshake!"
People are predicting that "I Drink Your Milkshake" is going to become one of those movie quotes that enters our lexicon - like, the Godfather's "I'm going to make him an offer he can't refuse.", Dorothy saying "Toto, I've got a feeling we're not in Kansas anymore." or Humphrey Bogart's "Here's looking at you, kid.".
