The story of Jack and the Beanstalk goes something like this:
Jack swaps a cow for some magic beans. Jack plants beans. Enormous beanstalk develops that stretches all the way to the clouds. Jack climbs the beanstalk (several times, in fact) and does a spot of breaking-and-entering at the home of a local giant (identifiable as such by both general size and the fact that he says fee-fi-fo-fum a lot). Jack gets himself into much trouble as a result. In the end, the beanstalk gets it.
Now, my theory is that Jack wasn’t so much in possession of magic beans but, rather, had applied too much manure to his vegetable patch. I base this on the fact that my garden is now home to several rather enthusiastic beanstalks which, I suspect, would extend all the way to the clouds if only I could find bamboo poles tall enough to support them. Instead, my french bean plants have chosen to wrap themselves around each other, weaving quite a tangled web in the process (which is probably just as well, because I would rather they didn’t head skyward and become a point of entry for visiting giants).
