The Wrong Stuff

Rollover joke - The phantom found Edward Everett Hale a century too early; by the time we invented satellites, the specifics of his 'brick moon' proposal were dismissed as science fiction.

See, it's funny because...building a spaceship out of bricks would be an amazingly bad idea. They're not airtight. They're heavy. They're just not what you should build a spaceship out of.

Then again, a wooden airplane built for World War II wasn't necessarily a great idea either.

Nor was a pykrete aircraft carrier.

The Trojan Horse, on the other hand, was clearly a great idea.
