the quarter

there were these two men approaching these two boys on a city street...one man says to the other..."watch me show you how stupid the kid on the left is"...he walks up to him and says..."hey , young fellow...do you want me to give you this shiny quarter...or this ugly old one dollar bill???"...the boy replies."i will take the quarter , sir"...the man gives the child the coin...winks at his friend...and then the two of them are on their way...the other child scratches his head and says..."why in the fuck did you not take the dollar???" the boy smiles and replies..."cause that's when the game ends".
