I have a friend named Mary Wise. I've known her through the STC for about 15 years now. She's a pip. Mary's a great technical communicator and was even the president of the STC at one point (which is no small accomplishment). Mary is also a professional clown. She's a Ringling Clown College graduate. And she's written a book entitled Girl Clown about her first job as a clown with a small circus.
It's a very good book. I just finished it a half hour ago and I needed to come tell you about it right away. You should buy a copy. Or even two.
