A high-end amplifier manufacturer makes the best amp he knows how to make. The circuit board is made in four layers, with ground plane on top and bottom so all traces are internal. This means you can't see what's connected where on the board.
The manufacturer then adds a bunch of cheap ceramic capacitors to the board. But these capacitors aren't connected to anything, so they do nothing whatsoever. He submits the amp to a high-end publication for review. The reviewer peeks at the circuit board, sees ceramic capacitors, then imagines all kinds of sonic anomalies. The amplifier gets a bad review.
Then the manufacturer modifies the amp based on this bad review. He replaces the ceramic capacitors with unobtanium Russian teflon capacitors, still not connected to anything. The amp is then resubmitted for review. The reviewer sees the teflon capacitors and imagines incredible sonic improvements. Then the new amp gets a rave review. The new amp measures the same, but the unbelievable sonic improvement just demonstrates to the reviewer "how little we really know about high-end audio".
The fly in the ointment with this gag is that the manufacturer would have to be willing to sacrifice his business due to the original bad review.
