Emma Thompson was on Saturday Night Live this past Saturday night as the guest host, and she had a little help during the opening monologue filling us in on what Mom really means.. Emma Thompson helps decipher what your mother is really saying with the help of Saturday Night Live veterans Tina Fey and Amy Poehler. Its hard enough to try and get into your mother's head on a daily basis, but these women have perhaps done all of mankind a great service and cracked the "Mom Code." Now, you never need to wonder is what she said, is what she meant!
