In memory of Ronald Reagan:

"The Sirius Cybernetics Corporation was awarded a huge research grant to design and produce synthetic personalities to order. The results were uniformly disastrous. All the 'people' and 'personalities' turned out to be amalgams of characteristics that simply could not co-exist in naturally occuring life-forms. Most of them were just poor pathetic misfits, but some were deeply, deeply dangerous. Dangerous because they didn't ring alarm bells in other people. They could walk through situations the way that ghosts walk through walls, because no one spotted the danger.

The most dangerous of all were three identical ones -- they were put in this hold, to be blasted...right out of this universe. They are not evil, in fact they are rather simple and charming. But they are the most dangerous creatures that ever lived because there is nothing they will not do if allowed, and nothing they will not be allowed to do...."

Zaphod slid aside a large ground-glass door. Beyond it lay a tank full of thick yellow liquid, and floating in it was a man...the kindly looking man in the tank seemed to be babbling gently to himself...Zaphod found a small speaker by the tank and turned it on. He heard the man babbling gently about a shining city on a hill.

He also heard the official from the Safety and Civil Reassurance Administration issue instructions that the planet in ZZ9 Plural Z Alpha must be made "perfectly safe".
