word - Craft the longest Scrabble sentence

This is another challenge along the same vein as similar challenges that have shown up on this site, requiring the puzzle to craft the longest possible sentence given a specific requirement.

What is the longest sentence with n words, where n is the number of Scrabble points that each of its words is worth?

Here is an example, for clarification, with Scrabble scores for each letter underneath:

She has two blue rental cars.  
141 411 141 3111 111111 3111

As you can see, the sentence has 6 words, where each word has a Scrabble score of 6.

Included for your convenience is a list of Scrabble letters by points:

1 point: e, a, i, o, n, r, t, l, s, u
2 points: d, g
3 points: b, c, m, p
4 points: f, h, v, w, y

5 points: k
8 points: j, x
10 points: q, z

Further rules:

• New rule: You cannot use words more than once in a sentence. I originally allowed this so that sentences like starplusplus's ("They couldn't teach what they should have taught; imagine trying!) would be possible (two uses of "they") - unfortunately, it's proved rather degenerate. While it's nice to know the longest possible sentence, let's find one that doesn't use methoxybenzenes 21 times.


• Proper nouns are not allowed, even if some form of the same word is in the Scrabble dictionary. This means you can't use "Bob" as a name even though "bob" is listed by another definition.


• In order for your answer to be accepted, you have to explain what your sentence means. Typing a 30-word sentence without explaining it will likely just confuse me!



• I'm not going to be super strict on punctuation, but be reasonable; semicolons, dashes and commas can be used to break the sentence into fragments, and contractions are acceptable as well.

(6/3/2015) Update: I'm no longer allowing use of the same word twice in a sentence. All other rules are still in play. I'm hoping this will make for more diverse sentences, as well as more interesting ones!

Answer

Extemporizing demythologizers demythologized overhomogenized, jackhammering azidothymidines; puzzlingly schizophrenic jazzmen diphthongizing hyperexcitement drizzlingly overemphasized jabberwocky jazziness, hypothesizing philosophizing jazzbos; quizzer psychochemicals hyperpolarized, contextualizing physicochemical jazzman phosphatization; remythologizing chazzanim blackjacking huzzahing quizzes psychologized nephrectomizing, zizzed pzazz.

I finally did this. The sentence is divided into four parts, and is quite... musical.

1. Ones who make ideas less mythical (and improvise along the way) did so to drugs used to treat AIDS that are overly uniform and operate jackhammers.


2. Jazz musicians confusingly diagnosed with schizophrenia who turn extreme excitement into a single syllable overemphasized (with light rain) characteristics of jazz with meaningless lyrics. Doing this, they expected to make jazz devotees act more serious.


3. Now, chemicals affecting behavior belonging to ones who write tests increased in potential difference. This added context to the physical and chemical treatment of jazz musicians using phosphates.


4. Leaders in prayer during Jewish services who create myths again and strike cheering quizzes with blackjacks psychologically interpreted the quality of excitement or attractiveness that surgically removes kidneys and makes buzzing sounds.

I used SOWPODS as my wordlist, with all words cross-checked against Hasbro's site. This is the longest possible sentence I could find.
