This week is three iconic Sesame Street cast members birthdays, three days in a row. Today is Sonia Manzano's (Maria) birthday. Yesterday was Roscoe Orman's (Gordon) birthday, and tomorrow will be Bob McGrath's. Sonia is turning 66 years old today, Roscoe just turned 72, Bob is about to be 84. Please help me wish them all a happy birthday, and share some of your favorite moments of the actors as well as their characters.
