Some lunatic actually created tomacco. The world is not only weirder than you think, it's weirder than you can possibly imagine. I used tomacco as an ur-crop for at least one set of hypothetical documentation on HighQ, the agricultural database that I do customer and technical support for. I seem to remember it was a demonstration of how to add a new crop and a new fertilizer to the system - in the hypothetical case, tomacco and plutonium fertilizer. The new tomacco hybrid was apparently created without benefit of poisonously radioactive fertilizers, much to my disappointment.
