About ten years ago, before I swore off talking to my dad at all, he tried to convince me that the FBI was trying to find him because he had “thought-up” how to build such a device. Now my dad is a barely-literate truck driver who lives in some small rural town in southeast Missouri—I had a hard time thinking he could just “think up” how to build something that has eluded thousands of actual scientists for decades, if not centuries.
Of course, the guy also claimed to be psychic and capable of astral projection, so I guess he can just break the laws of thermodynamics at will!
