A real MIB encounter

It was only afterwards, however, that Dr. Hopkins reflected further on the strangeness of his visitor's appearance and behavior. Particularly odd was the fact that his visitor stated that his host had two coins in his pocket. It was indeed the case. He then asked the doctor to put one of the coins in his hand and to watch the coin, not himself. As Hopkins watched, the coin seemed to go out of focus, and then gradually vanished. "Neither you nor anyone else on this plane will ever see that coin again," the visitor told him. After talking a little while longer on general UFO topics, Dr. Hopkins suddenly noticed that the visitor's speech was slowing down. The man then rose unsteadily to his feet and said, very slowly; "My energy is running low—must go now—goodbye." He walked falteringly to the door and descended the outside steps uncertainly, one at a time. Dr. Hopkins saw a bright light shining in the driveway, bluish-white and distinctly brighter than a normal car lamp. At the time, however, he assumed it must be the stranger's car, although he neither saw nor heard it.

Despite the fact that this story was completely fabricated.  I think it is interesting.  And so I've decided it is true. QED.
