Math rules!

From the dramatic side of life: The Playgoer has a list of the top 10 most produced plays of the past decade, and David Auburn's "Proof" is tops in a sprint. I saw "Proof" in the past decade (at Trinity Rep in Providence) and really liked it, but I haven't heard of a few of these. I'm inclined to buy the Playgoer's theory about why "The Glass Menagerie" gets produced over other, better Tennessee Williams plays, but a little shocked that it's the only "classic" up there.
