Small ostensibly fun puzzle

[Ben Wilson]

To celebrate the success of project hyper, your challenge is to write a coherent, flowing sentence with as many consecutive 10+ letter words as possible. No lists, no repitition whatsoever (so no crap like 'The derivations of internalise are internalise, internalising etc.).

Go.

[Charlie Reams]

Maybe you should stipulate no two consecutive words from the same part of speech, to prevent using a list of adjectives/adverbs.

[David Roe]

The incredibly inefficient International Coordinator, Marchioness Florentyna Featherstonehaugh, absolutely bamboozled Vice-President Christopher Mainwaring underneath Bournemouth's gloriously spectacular Graeco-Roman amphitheatre, shattering Christopher's confidence; whomsoever Christopher encountered thereafter infallibly recollected exceptionally unfortunate consequential embarrassments.

31, including 4 proper nouns, 1 repeated twice.

(I thought about giving the Marchioness a few extra middle names, but assumed that would be cheating.)

[Charlie Reams]

To paraphrase dear Nicholas, this is the best I can do without repetition, hyphenation or capitalisation:

Incredibly inefficient headmistresses, disgracefully dismissing definitively alternative viewpoints uncaringly, absolutely bamboozled remarkably unbelieving schoolchildren (consequently interrupted intellectually) underneath gloriously spectacular architecture underappreciated indefinitely, shattering persistently unqualified confidence indirectly; nevertheless whomsoever aforementioned schoolkids occasionally encountered thereafter infallibly recollected exceptionally unfortunate embarrassments unquestioningly.

Edit: On second thoughts it seems semicolons are basically cheating, because one can easily join arbitrarily many short sentences together with them.
Edit: On third thoughts even the "no consecutive parts of speech" rule isn't enough, because you can alternate stuff like "The unquestionably inefficient disgustingly attractive indecipherably impenetrable cat sat on the mat" which really isn't fun.

...as many consecutive 10+ letter words as possible...

[...] disgracefully [...] disgracefully [...]

Oops.

[Charlie Reams]

Fixed.

This puzzle is not really that fun.
