Star Wars: Shadows of the Empire Easter Egg - Funny Credits

Go to a file and name it or rename it _credits (don't forget the underscore.) Save the name and try to play any level. The end credits will show up, just like they always do, but where the regular credits would normally end, new ones pop up like "My sister was once bitten by a moose" (Monty Python) "This end up" and "Narf" (Pinky and the Brain.) There are tons and they're very funny.
