This movie was so funny, I couldnt stop laughing. It may have even made me experience heartburn for the first time. In the beginning of the movie, David Herman who plays Michael Bolton is rapping like a hardass in the car and then sees a black guy selling roses on the street and promptly locks his car door. Watch it! http://www.youtube.com/watch?v=gSje5N0VzlY.
Another notable scene was when Peter Gibbons (Ron Livingston) stops giving a shit about work and the movie goes through his carefree life to the song "Damn, it feels good to be a gangster". That is every upper middle class Americans daydream about how they wish they could be at work.
Too many great scenes to mention so just watch it its like a 100 minutes or something. Basically, it short, funny and sweet and the cast selection is perfect. If you work in high tech and are overworked, underpaid, undervalued and generally unnoticed for your efforts, this is your movie.
