Are you ready to "Wiig" out? Today funny lady Kristen Wiig turns 40, so we're celebrating with a look at some her most memorable Saturday Night Live moments. We've loved seeing more of Kristen on the big screen — especially after she killed it in Bridesmaids — but after seeing her as part of the SNL cast for seven years, we've missed her hilarious characters and impersonations. As we wish Kristen a happy birthday, let's look back at some of the best lines from her ladies, like Surprise Party Sue, Target Lady, Kathie Lee Gifford, Penelope, and "Tan Mom" Patricia Krentcil. Check them out now, and tell us: who's your favorite Kristen character?
