As an Easter egg in a program I once wrote I added a ‘silly menu’ that programmatically took a string of words, split by space, and generated an array of menu items each parented to the previous word’s. Then in the program code I had it generate the menu cascade from what was basically a paragraph of text. You would mouse through a paragraph worth of pop up menus zigzagging back and forth across the screen to finally get to the last one, which simply opened a message box with “Congratulations! You are now a certified mouseketeer.” Kinda lame but this post reminded me of it.
