According to the Hitchhiker’s Guide to the Galaxy by Douglas Adams (chapter 7) , Vogon poetry is the third worst in the Universe. The example given in the book goes:
Oh freddled gruntbuggly ..
?… thy micturations are to me
As plurdled gabbleblotchits on a lurgid bee.
Groop I implore thee, my foonting turlingdromes.
And booptiously drangle me with crunkly bindlewurdles
Or I will rend thee in the gobberwarts with my blurglecruncheon, see if I don’t!
So the contest is for the most effective creation of poem in the Vogon style that contains the the character string “zullo.”
Thanks to commenters for the idea.
