Read it through once

Some years ago there was living in Angels a man by the name of Jim Smiley, who was addicted to betting on everything. If he saw a fence he would bet you he could jump it; if he saw a horse he would bet you he could ride him; if he saw a frog he would bet you he could make him jump. If he told you his belief of anything, and you disputed it, you could always bet that he believed it; and if he had a mind to be agreeable he would bet you anything you pleased.
