Easter egg: On the DVD's Main Menu highlight the menu entry 'Play' and then press the 'Left' arrow key on your remote control to highlight the bottom left corner of the main TV screen in the background. Now press the 'Enter' key and you will have the chance to take a look at a special letter.
Easter egg: On the disc's main menu, wait for a couple of seconds. Kate's rump will appear and will do a stinky like her son (Stinky). Press your down button until you see PRRRP. Press your enter button to see a clip of Kate teaching you to spell the word "POOP" and some weird message that is saying stinky stuff. Whew. On the special features menu, go to the second page. Highlight the "Photo Gallery" menu entry and press your enter button to highlight S Club. Press your enter button to watch this.
Easter egg: The word Thirteen appears very briefly (a couple of seconds at most) as the main menu loads but is not clickable. However a video of the "Zen Chicken" can be accessed by disassembling the DVD to your PC. You can then save the video as a separate file.
