Top Blog Boing Boing tells us that McDonalds is trying to patent the sandwich, or at least a series of idiotic devices for making sandwiches. It goes so far to describe the proper way to assemble a hamburger on the piece of paper that you are going to then wrap the burger in. No prior art there, I'm quite sure.
The best part is found on pages 32-33 where they describe the "Method of Making a Hamburger Sandwich with Cheese." They actually include a line art drawing of a piece of burger wrapping paper with a target in the middle of it where the burger should be assembled (reference to figures 41-49 on pages 16 & 17).
"A food worker stacks, in order, cheese 42, onions 64, and a sliced pickle 68 on a staging area 142 of a hamburger sandwich wrapper 140. The staging area may be marked by indica 14Z as shown in FIG. 41 to assist the person who assembles the sandwich." (blah, blah, blah) "For a breadless sandwich leaf lettuce may be substituted for the bread crown and heel. Thus, in this sense the term "bread" or "bread component" also includes leaf lettuce or similar materials..."
So now lettuce is the new bread. You really can't make this stuff up. Truth is stranger than fiction. Here's a PDF of the patent app.
