Dr. Evil Feature
Go into the Special Features menu, stick around for 30 seconds and wait for the Evil rocket to take off through the middle, leaving behind the E logo. Click on the 'E' logo and get taken to an EVIL menu. In it you can find failed Evil plots from various movies and 2 links to Dr Evils songs in the movie.
NOTE: Some versions of the DVD will also have a 20-minute Comedy Central special acessible from this same location.
