The "Hugga Wugga" sketch was included in "The Muppet Show Book", published by Harry N. Abrams, Inc in 1978, in which the sequence was entirely illustrated by Tudor Banus.
This would be the first time The Muppets would do The Entertainer; Milton Berle would sing the lyrics in S:2 Ep.3.
Variations of the "Hugga Wugga" sketch were previously performed by the Muppets under the title "Sclrap Flyapp" on "The Today Show" (May 8, 1963); "The Jack Paar Program" (May 21, 1965); "The Mike Douglas Show" (July 19, 1966); "The Ed Sullivan Show" (November 24, 1968) and "The Tonight Show" (September 26, 1969). It was first performed under the name "Hugga Wugga" as part of Nancy Sinatra's Las Vegas stage show, Movin' with Nancy: Nice 'n' Easy, in 1971.
