Stanford contracts professor Richard Craswell conceived, wrote and performed these amazing songs about six of the most famous and memorable cases in contract law. I laughed out loud at the first one, but they all are simply brilliant. If, that is, you took first year Contracts.
UPDATE: By the time I had listened to all these songs and cut and pasted all the links into a blog post, I see that Eugene already blogged about these. But having the videos embedded might be more convenient for some, so I will leave it up.
