A Sesame Street Book Club book entitled The Sesame Street Alphabet Storybook (which interspersed different objects starting with subsequent letters into infamous stories as told by Sesame Street characters) included a quick telling of "The Princess who Never Laughed" using a xylophone and yo-yo's (X and Y) as props used by two people trying to make the princess laugh to no avail. It comes to end when Cookie Monster, who was lurking behind them, ate both items, which the princess did think was funny.
