I remember that Monty Python LP: it had one groove on one side and two on t'other, which made it a bar-steward to set up on student radio. The material for the latter were of course not *quite* of the same length; as it happens, the final sketch on the shorter one (a radio phone-in) ends with something with the form of "and I'm afraid we've run out of time". Cue five seconds' extra silence.

Until you mentioned it, Ray, it hadn't occurred to me that the argument which broke out between two of the callers in the sketch would have been mirrored by the fight between the lathe and the engineer. Another case of man vs excessive automation.
