S40, E8: It’s Stinky the Stinkweed's birthday! The Sesame Street friends decide to surprise him with lots of presents that they would like—but none of the gifts are quite right for a plant. Tune in for dancing in Abby’s Flying Fairy School, Elmo’s World of birthdays, and a toe-tapping High School Musical spoof. Ernie sings “In My Book” to Bert, and Maggie Gyllenhaal gets a surprise from Elmo and friends. Finally, Murray’s on the street finding out about the letter B and the number 17.
