Insert the sixth disc of the DVD set in your player and from the Main Menu go to the 'Bonus' section of special features. There use the direction keys on your remote control to highlight the 'Season 4' logo in the upper right corner of the screen and then press the 'Enter' key. This will give you the chance to view a hilarious party among the cast.
