This is a clip from the Albert Brooks movie "Modern Romance". He plays the editor on a movie being directed by the real life director James L. Brooks. They are trying to get just the right sound for the running, and the first time I saw it, I rewound it about six times, and I was crying I was laughing so hard. Albert Brooks is absolutely hilarious, and if you have not seen his movies, you should. His stand up and his voice work on the Simpsons is inspired as well.
