From Willy Wonka, "A little nonsense now and then is relished by the wisest men".  Words for everyone to live by.

From Bloodsport, "You taught me to never commit myself to one style, to keep an open mind!" This is how I feel about the fracturing of methodologies in economics.  People want economists to work across disciplines (with political scientists, psychologists, sociologists, anthropologists, etc.) but they fail to realize that many economists can't even work across methodologies in their own discipline.

From Real Genius, "Let the engineers figure out a use for it."  Sometimes we run experiments just to see what happens -- there is no policy issue or theory that we are testing.  Why do this -- who knows, let the engineers figure out why.

From the Gnomes Episode of South Park: "Phase 1, collect underpants.  Phase 2, ?.  Phase 3, Profit."  The basics of producer theory summed up by the Underpants Gnomes.  There are some inputs, there is some production process (black box), and then profit magically appears.

From Star Wars: Episode IV: "The ability to destroy a planet is insignificant when compared to the power of the Force".  Just think about the meaning of the Vader quote. 

From I, Robot: "Do you not see the logic of my plan?" VIKI    "Yes, but it just seems too ... heartless."   Sonny -- I have no real problem with the concept of homo economicus, but this exchange seems to capture the essence of the debate about homo economicus.

From A Beautiful Mind:  "You ever ... just know something, Dr. Nash?"  General  "Constantly" Nash

From A Beautiful Mind: "I have respect for beer." John Nash

From Weird Science: "We forgot to hook up the doll." - Wyatt.  I often wonder how many outcomes are different in experiments because there is some difference in experimental design.
