Ian Ayres, teaching American Contract Law as part of his Coursera-linked Yale lecture series, walks through Sullivan v. O'Connor, the case of a botched cosmetic nose surgery that became a staple teaching vehicle for contract remedies. Ayres uses the facts, a patient promised an improved profile who instead came away worse off, to explain the difference between expectation damages, reliance damages, and restitution, and why courts sometimes favor one measure over another when a promised outcome fails to materialize. The lecture works through how damages get calculated when the harm includes both a broken promise and physical injury, and what that means for how contract law treats service agreements involving personal well-being. It is a compact case lecture aimed at illustrating a doctrinal point rather than a general survey, with Ayres reasoning aloud through the court's logic step by step.
