It's a great time of year for reading the commencement addresses given by celebrities, as I'm reminded by a link on Wonkette to one Jon Stewart just gave. In case that whets your appetite, here's where you'll find more by Bob Newhart, Conan O'Brien, and Fred Rogers. I thought that I had found a link to one by Karen Ann Quinlan, but on closer inspection it turned out to be Anna Quindlen. To make up for that, here's one more, by Andy Rooney, and a picture of Steven Tyler.
