Frankenstein's monster
Widely held to mark the birth of modern science-fiction, Dr Frankenstein's monster (shown here in the 1931 film) was pieced together from multiple bits of dead bodies and animated by electricity. Although well-meaning, its hideous appearance led to rejection and gave it a crushing need for revenge.
IT moral
If your infrastructure is built out of heaps of old systems bolted together, don't be surprised if your users recoil in horror from the resultant ugly. That's going to feed back into the corporate willingness to spend on maintenance and doing things properly, and you'll only be able to patch things up for so long before the monster starts rebelling. Also, be careful before switching to alternative energy sources.
