Hadley Arkes, in his inimitable way, tells us how the first New Deal was, literally, laughed out of court. (Go to the clip at roughly 9 minutes for that part of the video).

That, and much else from the C-Span archives, are now available for free on the web.  I have been known to use a portion of this lecture, along with readings taking the other side, in my constitutional history classes. I imagine that there are countless other lectures now available that are equally useful for the classroom.  If readers here remember other such talks on C-Span, please note them in the comments.
