I had Fawlty Towers on the television, and this came on afterwards. Some fellow called The Doctor travelled to Sherwood Forest and met someone who apparently is known as Robin the Hood. Among one of the more odd features of this programme was the manner in which several of the characters helped a spaceship achieve orbit. This craft, hovering just above the earth's surface, nearly motionless, was able to make it to orbit with the help of the additional kinetic energy from an arrow bounced off of it. I'm not sure whether the arrow was made of some supermassive material (it was supposedly gold), or whether the large craft was really, really light.
However, more to my point today, I looked up the Wikipedia page on this programme. It mentioned that the very first episode was broadcast the day after Jack Kennedy had his head shot off.
Post your conspiratorial explanations for this "coincidence" here.
