The 1980 World Puppetry Festival was held between June 8th and 16th as a joint venture of the Union Internationale de la Marionette (UNIMA) and the Puppeteers of America. Jim Henson helped organize the week-long event which was primarily held at the Kennedy Center in Washington, D.C. and Georgetown University. The festival was attended by 2,000 puppeteers and helped gain attention to puppetry from the National Endowment for the Arts, an independent agency of the United States federal government.
A stage performance featuring Henson and the Muppets with several other famous puppeteers was taped for PBS and aired as Here Come the Puppets!. The special retained only a few of the Muppets' segments.
Ernie and Bert appear in the TV set. Bert complains that Bernice was left out of the previous number. He then rants about their hotel situation - Ernie gets the nice, double bed, leaving Bert with the cot and exiling Bernice to the windowsill. Ernie agrees to let Bernice sleep in the bed and he'll take the cot, then tells Bert he'll love the windowsill!
Kermit and Miss Piggy appear for a bit and perform a medley of songs ("Can't Take My Eyes Off of You," "Going Out of My Head" and "I’ll Never Love This Way Again"), then segue to Oscar the Grouch singing "I Love Trash" as Bruno the Trashman rollerskates around the stage.
At the end of the performance, Oscar and Bruno are joined by Sweetums, The Bossmen, some Muppet Birds, Doglion Beast, Mean Mama, Fletcher Bird, Betsy Bird and many other assorted large Muppets as Sweetums brings out Jim Henson, Frank Oz, and Caroll Spinney.
