McDonald's Secret Menu: revealed on NPR

The McChronicles just read an interesting article on npr.org regarding a secret McDonald's menu, known only to insiders. This article focused on only one of many alleged secret menu items.

With a little digging, The McChronicles uncovered a list of secret items from several fast food proprietors.
This image, from this site, depicts (from left to right): Monster Mac(8 beef patties!), Grilled Cheese, McGangBang(a double cheeseburger with a chicken patty in between the two beef patties).

Other interesting secret menu item names include (follow the link, above, to see more):

• McLeprichon (sic)
  
• McKinley Mac
• Pie McFlurry
  

The questions are:

To McDonald's crew: are these "real" secret menu items, or are they just things customers have made up - calling them secret menu items?

To customers: are you familiar with any of these items (listed at the 2nd link above)? And do you know of any others?
