quote:I bet a dollar to a doughnut that the chance an' the only one -- that every man in this room is simply achin' for, so that he won't look at any other, is the chance to make a lot of money!
Jerry is right.
All those words between 'chance' and the second 'is' -- are parenthetical. They are not necessary to make a complete sentence.
The words are written in the dialect of the speaker. He uses 'an' instead of 'and,' and 'achin' instad of 'aching.'
Those words in the middle are the characters' added comments about the chance to make a lot of money.
