The Royal Lackey made the the bed during a Sesame Street News Flash segment about the story of the princess and the cookie, as observed by reporter Kermit the Frog. The lackey struggles under the weight of the mattresses as he brings them into the royal bed chamber. He falls after putting the last mattress on the very top and again while helping Kermit count all ten.
After going through that, the lackey realizes he forgot the cookie and has to lift all the mattresses up to stick an oatmeal cookie underneath. His chore completed, the lackey hobbles off to see the court physician, fearing that he may have thrown his sacroiliac out of whack.
