A student fondly remembers his lying economics professor whose highly effective teaching technique involved a Lie of the Day in each of his lectures.
This was an insidiously brilliant technique to focus our attention -- by offering an open invitation for students to challenge his statements, he transmitted lessons that lasted far beyond the immediate subject matter and taught us to constantly checksum new statements and claims with what we already accept as fact.

Update: Scott Berkun suggests that this technique may have originated with a 1995 Neil Postman essay.
