Hello
They say laughter is the best medicine, after all.
True story: The scene is a conference of professors of marketing. The key note speaker is an eminent economist. The chairman, who sees himself as a bit of a wag, says,
"I would like to introduce my eminent colleague and friend. He's an economist, one of those people who turn random numbers into mathematical laws."
The economist, not to be out done, replies,
"My friend, here, is a marketer. They reverse the process."
