fatty, fatty, 2x4; can't fit through the kitchen door

If you're an In-N-Out aficionado, you know all about the "secret" menu items.  However, there are many lists online of dubious reliability claiming authority of these off-menu orders.  Luckily for us, John Marcotte of Badmouth has done some actual research on this and provides an up-to-date illustrated compendium of In-N-Out secret menu orders on which even a reference librarian could rely.  News to me: these "secret" orders may not be on their consciously-simple menu, but they are hardly non-corporate.  If you order your lunch Animal Style, "Animal Style" appears on your computer-generated receipt.

A “2×4″ is a burger with two beef patties and four slices of cheese. You can also order a “3×3,” a “4×2″ or any other meat/cheese combo your little heart desires. In the past, we’ve seen burgers as large as a 100×100, but In-N-Out changed their policy and now a 4×4 is as large as you can get.
