Work the Shell - Mad Libs Generator, Tweaks and Hacks

We continue building a Mad Libs tool and slowly come to realize that it's a considerably harder problem than can be neatly solved in a 20-line shell script.
But, There Are Problems

Looking back at what we've done, however, there are a couple problems. The most important is that although we have a tool that identifies part of speech, it's not particularly accurate, because it turns out that many words can be identified properly based only on their use and context. A grammarian already will have identified some of the problems above! Even more than that, I suspect that however much we hack the script to make smarter word selections and identify context, the fact is that creating a really great Mad Libs involves human intervention. Given an arbitrary sentence, there are words that can be replaced to make it funny, and others that just make it incomprehensible.

Now, it wouldn't be too much to have a somewhat less ambitious program that understood a Mad Libs type of markup language and prompted as appropriate, reassembling the results after user input. Perhaps “The <noun> in <place> stays mainly in the plain”, which turns into:

Noun (person, place or thing):
Noun (a place):

But, that I will leave as (ready for it?) an exercise for the reader!
