The double dactyl is a verse form invented by Anthony Hecht and Paul Pascal in 1951.[1]
Like the limerick, the double dactyl has a fixed structure, is usually humorous, and is rigid in its prosodic structure. The double dactyl's prosodic requirements are more strenuous due to its increased length, and its specific requirements as to subject matter and word choice much more rigid, making it significantly more difficult to write.
There must be two stanzas, each comprising three lines of dactylic dimeter ( ¯ ˘ ˘ ¯ ˘ ˘ ) followed by a line consisting of just a choriamb ( ¯ ˘ ˘ ¯ ). The last lines of these two stanzas must rhyme. Further, the first line of the first stanza is repetitive nonsense, and the second line of the first stanza is the subject of the poem, which in the purest instances of the form is a double-dactylic proper noun. (Hecht and other poets sometimes bent or ignored this rule, as in the Robison poem below.) There is also a requirement for at least one line, preferably the second line of the second stanza, to be entirely one double dactyl word. Some purists still follow Hecht and Pascal's original rule that no single six-syllable word, once used in a double dactyl, should ever be knowingly used again.[1]
An example by John Hollander:[1]

Metapoetically, Roger L. Robison crafted this poem describing itself:

The Dutch version, called after a children's verse, was introduced in the Dutch language by Drs. P.[2]
A McWhirtle is a light verse form similar to a double dactyl, invented in 1989 by American poet Bruce Newling. McWhirtles share essentially the same form as double dactyls, but without the strict requirements, making them easier to write. Specifically:
The looser form allows poets additional freedom to include additional rhymes and other stylistic devices.
The form is named after the fictional protagonist in an early example by Newling, included with his original written description of the form, dated August 12, 1989; but his first McWhirtle, in which his friend "Skip" Ungar is the protagonist and which also appeared with his original description, was:
The Piano Player
I read in the papers
That Harry F. Ungar
Performs in a night spot
Near soigne Scotch Plains,
Caressing the keyboard
While affluent yuppies
Are eating and drinking
Their capital gains.
The first published description of the McWhirtle, with examples, was in E.O. Parrott, ed., How to Be Well-Versed in Poetry, London: Viking, 1990, pp. 197–200; and the verse form was also described in Anne H. Soukhanov, Word Watch - The Stories Behind the Words of Our Lives, New York: Henry Holt and Company, 1995, pp. 388–89.
An example by American poet Kenn Nesbitt:
Fernando the Fearless
We're truly in awe of
Fernando the Fearless
who needed no net
for the flying trapeze.
Alas, what a shame
it's surprisingly difficult
catching a bar
in the midst of a sneeze.
