When you click on the in-game credits, there is advertisement indicating the soon to be released title Larry 8: Lust in Space. The game was never completed or released.
Go to any area of the game where there are no animations or movies playing. (i.e. not the credits). Type in the word "alshead", minus the quotes, and hit enter. Al's head will bounce around the screen at a speed in ratio to the speed of your computer. His eyes follow your mouse. Double click a lot around his nose and a one dollar chip will increase your wealth.
