Anything that comes out of his mouth is a trainwreck of autism that makes it sound like his brain is trying really hard to come up with a sentence. I have so many I don't know which one to really choose.
My favorite one I think of is
"I lifted and carried her doghouse to the site where we buried her. Her doghouse. That thing had to weigh, like, five, ten tons."
"I work, I work hard for my father in his, in his gar-, in his gar-, in his garden! I pulled weeds! Those weeds are very hard to pull!"
"I'M WORKIN ON IT!!!!!!!!!!!"
"SONIC ARMS ARE NOT BLUE!!!!!!!!!!!!!!!!"
"Who hasn't dreamed about having sex with their mother?"
