Flipping through channels this evening, I saw a new ad for the McDonald's dollar menu. The ad ends with the announcer saying, "I'd buy that for a dollar." That phrase comes from the dystopian sci-fi movie RoboCop, in which it is a catch phrase for a crass, Benny Hill-esque TV show that entertains the degenerate citizens of future Detroit.
What could McDonald's possibly be trying to say with this ad? Has the phrase filtered out into pop culture so far that it is free of its roots? I could be wrong about its roots, I suppose. This forum links it to a sci-fi short story with the phrase "Would you buy it for a quarter?" But a little google research suggests the "dollar" version is indeed from RoboCop.
