Katie Couric’s speech to Princeton’s graduating class contained a sobering message to female grads—don’t bank on an MRS degree. “You may also have a dream of being married and having a family, and at some point the career may take a backseat. There is no more challenging, rewarding or important job than being a mom. I just want to say this—sometimes dreams of domestic bliss are interrupted by reality. People get divorced. People die. You need to protect yourself,” she said. Couric spoke of her own marriage, when her husband died nine months after being diagnosed with cancer, leaving her with two small children. “Luckily, I had a career and therefore the financial independence to support my children.” The speech wasn't all serious—she also poked fun at a relatively easy target: Rush Limbaugh.
