Happy birthday to me! If you'd like to make me a cake, feel free to make this one. As for the currency inside, how about hundred dollar bills? That's not too much to ask, right?
All of the patents listed on this page were officially issued by the U.S. Patent Office. Don't blame me for inventing them or successfully prosecuting them to grant: I'm only a legal assistant in the nebulous patent world. My only wish is to share the oddities of human imagination, as exemplified by the weirdnesses herein. Don't think that I own any of these products, either. Chances are they don't and never will exist anywhere beyond writing; they say that only 1 out of 20 patents actually makes it into the tangible world. With over seven million U.S. patents granted so far, that means most of those inventions are, well, just words.
