Say what?

Y'know the phrase "I'm a (insert adjective here) person stuck in a (insert opposite adjective here)'s body"?
Well, I realize how ridiculous this may sound, but I think my son may be an Aspie stuck in an Autie's body. Or however I should say that so I'm PC. Okay- stop laughing, I'm only half joking. My son is Autistic. Has Autism. Whatever. He has a language delay, but there are times when his chatter will make your head spin.

Jaysen has the desire to have the lengthy focused discussions characteristic to Aspergers, minus the ability to be so loquacious in doing so.
And when he gets geared up, he often sounds like this:

So...mommy. I was thinking.
What were you thinking, sweetie?
I was thinking... I gonna moooove to America.
You're in America.
No, I gonna move to America far away inna trees and sand.
(America is apparently an island?)
Do you mean Australia?
Australia. I go there and soupcase and veeo and DVD and plaaaaaay...(he usually trails off here)
..and then I be there, and sand and trees and veeo, and...

Get the idea?
It gets even more interesting when he talks to himself (sans moderation):

Hey Jaysen-
Yes, Jaysen?
What are you do there?
Oh nuffing. I just here to go to see.
Okay! Let's go!
Okay! What you do now?
Oh... couch, and horses, and juice, and pillows.
Hey- do you like Baby Einstein?
Yes- I like Baby Van Gogh. C'mon, let's see.
Look! Over there!
Beethoven?!? Beethoven! What are you doing with the kraz...nickerflay?
I don know there!
Well...beideroud niff carts.
In pants?!?
Yes! In pants!
Oh no!

And the beat goes on.
Once he gets ahead of his internal "script", any word is fair game- even made up ones.
He'll talk to me, he'll talk to himself, he'll talk to his tapes, he'll talk to invisible friends (not imaginary because they're real people, just not present at the time), it just doesn't matter.
He will talk and talk and talk, and the more he talks, the less sense he makes.

And if he's talking to you? You better have some kind of answer for him if he asks you a question- even if the answer is "floor wax".
