1)Mark Twain introduced Simon Wheeler as the narrator he tod him to be. Simon Wheeler is used as a funny narrator. "Thish-yer Smiley had a mare the boys called her the fifteen- minute nag." The way he puts his words together shows incongruity. Readers wouldn't really pay attention to what Simon is saying but the way he says it.

2)It makes his sentence sound funny and he can get off topic with his words a little bit. "but always at the fag-end of the race she'd get excited and desperate- like, and come cavorting and straddling up, and scattering her legs around limber, sometimes in the air, and sometimes out to one side amongst the fences, and kicking up m-o-r-e dust, and raising m-o-r-e racket with her coughing and sneezing and blowing her nose and always fetch up at the stand just about a neck ahead, as near as you could cipher it down."

3)The narrator seems to be saying everything weird about the characters but doesn't see himself as weird. He seems to know what he is talking about more than the characters in his explanantion.
