Dumpert Originals: Mahna Mahna

In 1969, the first season of Sesame Street featured a sketch featuring two Muppet girls who are unsure of what to do, until they decide to sing a song, enter an unusual-looking version of the latter Muppet character Mahna Mahna (whose named was later changed to Bip Bippadotta, so as to differentiate him from the Mahna Mahna character on The Muppet Show) who begins singing "Mahna Mahna", prompting the girls to join him.
