Huck's first encounter with the two comes about as they were being chased by men with dogs - both had been working their particular scams in the same town. They are both dressed in tattered clothes and carrying worn-out suitcases. The main physical difference, aside from their age, was that the elder was bald.
The younger of the two, who claims to be "the rightful Duke of Bridgewater," had been "selling an article to take the tartar off the teeth-and it does take it off, too, and generly the enamel along with it." The elder, not to be outdone by the young man he has just met, is forced to confess that he is "the pore disappeared Dauphin, Looy the Seventeen, son of Looy the Sixteen and Marry Antonette." Clarifying the impact of hardship upon his appearance, he confirms, "Yes, gentlemen, you see before you, in blue jeans and misery, the wanderin', exiled, trampled-on and sufferin' rightful King of France."
As time goes by, it becomes obvious that both are experts at creating fantastic schemes calculated to separate the country hicks they consider all the folk living along the river to be from their money. They will try anything that might net them a profit, and don't hesitate to press Huck and Jim into service whenever it helps to further their plans.
