Public Speaking Course:
My public speaking course teaches you how to use definitions that give the audience a quick, comical twist on a word they already know. Be sure that the word defined is relevant to the point you are trying to make.
Here are some definitions that I like:
Banker: A fellow who lends you his umbrella when the sun is shining and wants it back the minute it begins to rain. ~~ Mark Twain (with a similar quotation by Robert Frost).
Just make sure you know your audience well before using any comical definition. You wouldn't use this one if you were talking to bankers, but if you are a banker talking to nonbankers you could change it to read like this:
"Some people say that a banker is a person who lends you his umbrella when the sun is shining and wants it back the minute it begins to rain. As a banker, I want you to know that is not true. I would lend you my umbrella anytime at X percent above prime with two points.
(Possible extender line) If you want to borrow MONEY, that's a different story."
City Life: Millions of people being lonely together. ~~ Henry David Thoreau
Death: To stop sinning suddenly. ~~ Elbert Hubbard
Jury: Twelve persons chosen to decide who has the better lawyer. ~~ Robert Frost
Radical: A man with both feet planted firmly in the air. ~~ Franklin Delano Roosevelt
Song: The licensed medium for bawling in public things too silly or sacred to be uttered in ordinary speech. ~~ Oliver Herford
Zoo: A place devised for animals to study the habits of human beings. ~~ Oliver Herford
There are tons of these definitions available in comedy books, quotation books, and books for public speakers. In many cases you will have several choices from many different topics. I probably had at least 20 choices on the subject of conservatism alone, and liberals are a laugh a minute. (just joking,,,)
