Those words are not enough

There are some crazy words in this language of ours. English is of course the one of which I speak. I like a lot of words. In fact, I just plain like talking. When I do, here are some of my favorites:

asps -- Doesn't sound that vicious, does it? It is one animal that can say its own name, however.
aardvark -- Makes use of the classic "rdv" combination. Plus the two A's put it over the top (of the dictionary). Looks remarkably like "Harvard". Watch this transformation now, watch this: Harvard => Hardvard => Aardvard => Aardvark. See? I don't know if aardvarks can say their own name, but I doubt it.
aa -- While we're talking about words that start with "aa", how about "aa"? It's lava. Rough lava.
awkward -- It looks its definition. In addition, with a little work, awkward could become aardvark too. I'll leave the details to you.
cwm -- one of the best words to use in Scrabble if you run out of vowels. It means coal, or lightning, or a cat in panama, or something like that. I forget.
critwigm -- Even better Scrabble word than cwm. Very difficult to make this one aardvark.
gimcrack -- Sounds like what you see when your plumber Jim bends down. Definition: A cheap and showy object of little or no use; a gewgaw.
gewgaw -- Definition: a gimcrack. Origins unknown (because it was the result of a sneeze?)
onomatopoeia -- One of those words you only ever use in high school English class, or if you want to prove you were awake in high school English. But fun nonetheless
rhythm -- Close friend to rhyme. I like them both, but rhythm is my favorite.
serendipity -- Not sure why, but that's just fun to say. Like Francisco. Francisco...
succinct -- awkward to say, and unlike awkward, does not fit its own definition.

See, now wasn't that fun? What am I missing?

If you saw this coming towards you, you'd say "AA!"

"The aa is heading towards the cwm with the rhythm of a critwigm, so grab your gimcracks and gewgaws and skedaddle!" the awkward aardvark succinctly said to serendipitous asps. "Onomatopoeia," he yelled to prove he passed high school English.
