``If the circus is coming to town and you paint a sign saying ``Circus coming to the show ground Saturday``, that's advertising. If you put the sign on the back of an elephant and walk into town, that's promotion. If an elephant walks through the mayor's flower bed and the local newspaper writes a story about it, that's publicity. And if you get the mayor to laugh about it that's public relations. If the citizens go to the circus, you show them the many entertainment booths, explain how much fun they'll have spending money at the booths, answer their questions and ultimately they spend a lot of money at the circus, that's sales. And if you planned the whole thing, that's marketing.``
