Improv Classes in DC:
Washington Improv Theater is looking for students to fill its intro improv classes. I took classes with these folks several years ago, and they are lots of fun, and also a good way to overcome shyness about speaking/performing in front of groups. If you're a local big-firm associate, you might even be able to get your firm to pay for your class, as will teach some useful skills. Even if not, many of my former classmates pointed out that "it's a lot cheaper than therapy."
