Here's one for Kyupol: if you use Firefox, Cameno, SeaMonkey, Mozilla or any other Mozilla browser paste about:mozilla into the adress bar and press enter to get a wierd message from the Book Of Mozilla.
There's a whole list of interesting ones for design programs and other things here.
I like the little one in Illustrator:
Opening the Selection pop-up menu at the bottom of the artwork window while holding down the Alt key, brings up some interesting added options: moonphase, number of mouseclicks, Illustrator units sold, shopping days ‘til Christmas, eyes â€“ a set of eyes that follow your cursor around the screen â€“ and Mordy’s homenumber. (Mordy Golding worked at Adobe as product manager for Illustrator 10 and Illustrator CS. That's not his home number you get though, it's Adobe tech-support)
