This is the speech. Remember to pronounce Nazi as Narzee, which was something which particularly annoyed Hitler.
That is just the standard British way of mangling words assimilated from foreign languages. Back in my college days we called it the Don JOO-uhn Principle. I've heard Brits pronounce
tequila as tee-QUILL-ah and of course their three-syllable version of the word kha-GWAHR, which they use as an auto marque, is infamous. We don't pronounce any of those words quite right either, but at least they all have the correct number of syllables and the accent on the correct one. We're actually pretty close with te-KEE-luh.
The punctuation here is so strange, that I think it must be original. Two sentences.
The punctuation is nonetheless proper, if indeed strange. I wonder whether he dashed it off, intending for it only to be spoken, not distributed in writing. Even the best writers slack off when aiming for oral rather than written eloquence. It could be that the punctuation was "cleaned up" later. In those days he might very well have never given anyone his own written draft; what we're reading may be a transcription after the fact by journalist on staff.
In any case the hypozeuxis form is so weak that it makes a poor example. Caesar's is much more powerful, especially in the original language:
Three verbs, all standing alone with no subject, all in the preterit tense. Of course in Latin a hypozeuxis may be far more compact than in English, since the verb inflections include an implicit subject. Churchill's example is woefully deficient in parallel construction, and I doubt very much that such a master of the King's English would have submitted that draft for print media.
Nerd: A bookish but likeable individual with few friends.
A definition steeped in irony. Likeable individuals generally have many friends.
Etymology: I like "Drunk" backwards, Knurd, becoming nerd.
That's suspicious. A common trait of nerds is unflagging seriousness and pedantry, reflected in moderation or total abstinence from alcohol. A drunken nerd is a rare sight and usually confined to first-year university parties.
Dork: Need not be particularly clever. Socially and physically clumsy. Most likely of the three to end up in prison. Etymology: Unknown. Supposed to be the word for a Whale's Penis.
When I first heard the word in the 1960s it was a variation of calling someone a "dick," and occasionally the word was used as a verb for intercourse performed with no thought for the partner's feelings--or even her name.

So a Dork is indeed a big, clumsy Dick. But in those days there was no overtone of malice or true antisocial behavior. Dorks were unpopular but we would not have expected them to ever be arrested. (The legal doctrine of "date rape" was several decades off, of course.)
Geek: A nerd whose main interest is computers. Most likely of the three to end up being a millionaire. Etymology: From an old word for fool, eg in Shakespeare's Twelfth Night
Missing an important step here. In the early 20th century and presumably the 19th, a geek was a very specific member of circus and carnival troupes. (The squeamish are advised to skip the rest of this paragraph). My father's generation was quite familiar with the word, meaning, "A performer who bites the heads off of live chickens for entertainment." The only true "geek" alive today is Ozzy Osbourne, and he is indeed fairly wealthy.

I believe he has reformed since the "cute little rubber bat" that the fan threw onto the stage turned out to be a real one and he had to undergo the ignominious treatment for suspected rabies.
The words all have four letters. Words with four letters which describe types of people tend to be disparaging, eg Yank (American) Prod (Protestant) Brit (English person)
Odd. We Americans don't feel disparaged when Europeans call us "Yanks." Southerners bristle a bit: a Yankee is a Northener, a term that survives from the Civil War. WWII was a strong force for reunification of our country; soldiers were touched by the experience of Yankees and Rebels fighting on the same side and endured being lumped together by the grateful Europeans. I don't believe that any American means "Brit" to be an insult; I toss the word around myself on SciForums and I certainly hope no one has taken offense. I hate to call the present-day inhabitants of the south of Great Britain "Britons," since they are the descendants of Germanic occupiers who marginalized the true Celtic Britons, and of course of the subsequent Norman French occupiers who carried on the tradition. The Scots have a better claim to the name since they are at least a Celtic people.
