Raiders of the Lost Ark Easter Egg - Programmer's Initials

Make sure you have the Chai in your inventory, followed by a parachute. On the mesa field, make your way to the large mesa in the center that is shaped like a flying saucer. With the item cursor on the Chai, walk off the side of the mesa. As you are falling, drop the Chai in mid-air. A Yar (from Yar's Revenge) will appear at the top of the screen. Quickly activate the parachute to avoid being killed from falling. Complete the rest of the game. At the end, when you see your final point total, the initials "HSW2" appear in the inventory bar. This stands for Howard Scott Warshaw, the programmer. He also hid his initials in both Yar's Revenge and in E.T. for the Atari 2600.
