Larry Laffer, a fictional character from the Leisure Suit Larry game series
The basic concept was not new; Laffer himself says he learned it from Ibn Khaldun and John Maynard Keynes.
In November 2001, he criticized economist Arthur Laffer (recently appointed an advisor to Florida Governor-elect Rick Scott), saying Laffer's economic theory "basically doesn't hold water".
Larry Laffer made a homage-type cameo appearance in the Spaceballs: The Animated Series episode "Grand Theft Starship" and was referenced by Charles Stross in Asimov's Science Fiction.
