A friend of mine years ago had a cousin who was a bit of a speed freak. He'd have sessions that lasted for days. During one of his manic 3 day "sessions," he'd apparently disappeared into his garage for hours at a time, saying he was "working on something amazing." As a teaser, he told everyone it was some kind of epic DJ entertainment center which incorporated lasers, strobes, a huge sound system, turntables etc. Some kind of all-in-one console which would transform any party. So he'd go into the garage for a bit, do more speed, come out, lift some weights for a bit, do more speed, go back into the garage. And so it went on for 3 days and nights, until finally he announced that the gizmo was complete, that he was "coming down," would hit the hay for a few hours, and have everyone over for the grand unveiling once he'd woken up. So hours later everyone showed up and banged on the door to wake him up. Bleary eyed, he showed everyone into the garage and took the dust sheet off his creation. And apparently it was just some old hi-fi system onto which he'd taped a load of random junk. Everything had wires coming out of it that seemed to be connected randomly to other things with no logic behind it at all. Some of the wires weren't even connected to anything. Then he plugged it in, flipped a switch and.....nothing. Everyone went home.
