American Psycho: My name is Patrick Bateman.
One of my favourite scenes from American Psycho. It sets the tone of the movie well, the routine described/shown is completely ridiculous and also serves as a good little introduction to the lead character Patrick Bateman. And I love Christian Bale's voice-over here, it's somehow stupidly soothing to me lol. I wouldn't consider this spoilery since it's from about 5 minutes into the film, but it's definitely NSFW.
