Monkey Island 3 (Curse of Monkey Island) Easter Egg - Spider in the Crypt

On Blood Island after Stan the salesman has turned the generic crypt into "The Mutual of Stan", walk inside and examine the "giant web" in the top left of the screen.

Guybrush will ask "I wonder where the spider that spun that web is?".
Now leave the crypt and re-enter it approximately 40 times. Eventually you will enter the crypt and see a tiny woman struggling to get free of the giant web. It is Maggie from another Lucasarts adventure, "The Dig." A spider will climb down the web towards her, mirroring a similar scene that takes place in "The Dig".
