Totallyabsurd.com has hundreds of dumb drawings they claim are illustrations for real US patents. I doubt they are legit, but you decide.  They are pretty funny and definitely weird, so I considered them fair game for this site. My only question is about the “Remote Control Horse.” Why would anybody have a remote controlled horse? It would take a really geeky cowboy to guide his horse with a joystick. Enjoy.
