Broadway stars have a long history with Sesame Street. From the hilarious banter of Madeline Kahn and Grover to more recent appearances by Tony winner Lin-Manuel Miranda (as a bird real estate agent), Neil Patrick Harris (as the Fairy Shoe Person) and Broadway hunks Hugh Jackman and Jude Law helping close the vocab gap with the segment "Word on the Street." Now married Broadway couple Idina Menzel and Taye Diggs are doing their part to teach new words to viewers. We predict their young son, Walker, is going to go nuts when he sees his parents on the show. Check out the adorable duo as they get sneezy and itchy with their Sesame friends.
