"Fun's No Fun at All (Gonna Have Fun Tonight)" is performed by the Fraggles in the Fraggle Rock episode "Boober and the Glob." Everyone except Boober is excited for the beginning of Joke Day, and they try to draw him into the silliness. However, Boober resists out of dislike for Joke Day and fear of the glob that has appeared in Fraggle Rock.
