Wikipedia: Ventriloquism
Ventriloquism, or ventriloquy, is an act of stagecraft in which a person (a ventriloquist) changes his or her voice so that it appears that the voice is coming from elsewhere, usually a puppeteered “dummy”. The act of ventriloquism is ventriloquizing, and the ability to do so is commonly called in English the ability to “throw” one’s voice.
 
Wikipedia: For Dummies
For Dummies is an extensive series of instructional/reference books which are intended to present non-intimidating guides for readers new to the various topics covered. The series has been a worldwide success with editions in numerous languages.
 
The books are an example of a media franchise, consistently sporting a distinctive cover—usually yellow and black with a triangular-headed cartoon figure known as the “Dummies Man”, and an informal, blackboard-style logo. Prose is simple and direct; bold icons, such as a piece of string tied around an index finger, are placed in the margin to indicate particularly important passages.

Leo Brodie, Julian Noble, Jack Woehr and all the other Forth book authors out there have done well, all things considered, but the clown who turned out ‘Perl in 21 Days’ probably made more in 21 days than Brodie, Noble and Woehr made combined from their efforts!  And the guy who came up with ‘Ventriloquism for Dummies’ 😊 and its ilk probably could buy his own Cray by now.
