In the musical The Music Man, the travelling salesman and con artist Harold Hill, who claims to be a professor of music with a unique learning method of playing a tune by merely thinking it over and over, arrives at the backwater town of Rapid City, Iowa, where he hopes to make a killing by selling marching band instruments, uniforms, and instructions to a rather naive populace. Harold Hill's usual modus operandi is to capitalize on a local issue he can exploit, sweet talk people into believing he can turn musically challenged boys into band member by means of his unique "Think System", sells them the complete outfit for a marching band, collects the money, and skips town as soon as the merchandise arrives. Of course, in this case something got in the way in the form of a sceptical local librarian whose research reveals that he is not what he claims to be. But they soon falls in love with each other, and she hides the truth about his credential from her fellow town folks, while "Professor" Hill decides to stay on to teach the boys how to play by using his "Think System".
 
The jig is up when another travelling salesman arrives and exposes him for what he is. Being a light-hearted musical, naturally there is a happy ending. When  the angry mob cornered Harold Hill, his faithful students miraculously turn into a full fledged marching band dressed in their finery and comes marching down Main Street playing "Seventy Six Trombones".

In real life seldom are we so lucky; miracles don't come everyday. Dream merchants with forked tongues will sell you, at exorbitant prices, panacea that either won't work, or at best, gives a superficial temporary reprieve of your chronic condition. Of course some people will attest to their effectiveness; there is always that placebo effect. Just keep in mind, "If something sounds too good to be true, it often is."  Caveat Emptor, my friend, caveat emptor! 更多信息请访问：http://www.engbus.cn/

For the snake oil salesmen out there, "You can fool some of the people all of the time, and all of the people some of the time, but you cannot fool all of the people all of the time."
