Supposedly, The rock organ was about 11 seconds long. The attempted to smuggle a forbidden test of the pitch box onto the air. Rumor has it they partially succeeded: the 11 seconds of this video but then it was taken off the air and a different one was broadcast instead.
A few people claim to have seen it in those 11 seconds, but trying to tell then something that had happened with the test's premiere.
This has all been dismissed as a prank until a test pitch box was found by a woman named Alyssa Goodman, she says that she now has a phobia of a test box. She fears that the giant rocks was a rock organ may have had the same fate, and she can't bear to think of that.
