Referenced in the first draft script of the Star Trek: Deep Space Nine seventh season episode "The Changing Face of Evil", "Howl" is a poem by Allen Ginsberg, written in Earth's 20th century. The poem had the lines, "I saw the best minds of my generation destroyed by madness." The aforementioned script included a scene in which Morn had just given a recital of "Howl" in Quark's.
In the scene, Kira Nerys attempted to describe "Howl" to Ezri Dax, who had missed the recital, Kira stating, "I guess you'd call it an epic poem." Though Dax then assumed the poem had been written by Morn himself, Kira replied by clarifying it was "an ancient Earth poem" and by unconfidently identifying it by name. However, Dax wasn't familiar with the poem, even when Kira recited some of the lines from it. She went on to comment that the poem was "really quite moving" and was "all about social unrest and the quest for personal freedom", which Dax thought sounded interesting. When Julian Bashir approached, he remarked that the poem, which he also mistook as having been written by Morn until Kira clarified that this wasn't so, had been "really quite good."
