I stumbled on this scene on youtube this morning (and no, before you ask, I wasn't searching for 'dick') from one of my favourite films The Rules Of Attraction. This scene cracks me up!
Russell Sams as spoilt gay rich kid Richard decides to disrupt a lunch with his boozy mother (Swoozie Kurtz) and the equally boozy mother of his friend Paul (Ian Somerhalder) played by Faye Dunaway. Sams takes off and all the other actors can do is hang on for dear life and go along for the ride.
Oh, and if you are watching this at work... well, the language is very NSFW.
