The Disguiseinator is not really an invention, because it is Joe's eyebrows. For use, he simply tears his eyebrows off, slowly, and then once they come off, he can wear it like a mustache. The pain that comes out of this process was the inspiration for the successor to this inator, the Moustachinator. Now he uses the Moustachinator so that he can keep his eyebrows (somewhat) firmly attached.
