Why can't ChatGPT write a poem praising Trump? It's too hard to make a rhyme for "orange."

We were talking about the failure of ChatGPT to write "a poem about the positive attributes of Donald Trump" (when it easily composed "a poem about the positive attributes of Joe Biden").

Most of the discussion at the link is about the problem of bias in ChatGPT. But commenter Bob Boyd — taunting "Eat your heart out, ChatGPT" — wrote his own poem:

Skin of orange 

He's just like Hitler 

Except for his hair 

And his hands are littler

Of course, being "just like Hitler" is not a "positive attribute" — in fact this is the opposite of a poem of praise — and there's still no rhyme for "orange." But there's an apt rhyme for "Hitler," and there's the push that gets us to think of the age-old problem of rhyming with "orange."

Maybe it's easier to rhyme "orange" in German. Checking the English-to-German translator, I see the German for "orange" is "orange."

There's a Wikipedia article on the word "orange" — the word, not the color, not the fruit — and it's mostly devoted to the subject of rhyming with "orange":

No common English word is a full rhyme for "orange", though there are half rhymes, such as "hinge", "lozenge", "syringe", and "porridge". Slang and otherwise uncommon examples exist. Although this property is not unique to the word—one study of 5,411 one-syllable English words found 80 words with no rhymes—the lack of rhyme for "orange" has garnered significant attention, and inspired many humorous verses.

Ah! A "garner" in the wild.

Although "sporange", a variant of "sporangium", is an eye rhyme for "orange", it is not a true rhyme as its second syllable is pronounced with an unreduced vowel [-ændʒ], and often stressed.

There are a number of proper nouns which rhyme or nearly rhyme with "orange", including The Blorenge, a mountain in Wales, and Gorringe, a surname. US Naval Commander Henry Honychurch Gorringe, the captain of the USS Gettysburg, who discovered Gorringe Ridge in 1875, led Arthur Guiterman to quip in "Local Note":

In Sparkill buried lies that man of mark

Who brought the Obelisk to Central Park,

Redoubtable Commander H.H. Gorringe,

Whose name supplies the long-sought rhyme for "orange."

The slang word "blorange", a hair color between blond and orange, is a rhyme. It is attested from the early 2000s and appears in fashion-related media from about 2017.

Various linguistic or poetic devices provide for rhymes in some accents.

Compound words or phrases may give true or near rhymes. Examples include "door-hinge", "torn hinge", "or inch", and "a wrench". William Shepard Walsh attributes this verse featuring two multiple-word rhymes to Walter William Skeat:

I gave my darling child a lemon,

That lately grew its fragrant stem on;

And next, to give her pleasure more range,

I offered her a juicy orange.

And nuts, she cracked them in the door-hinge.

Enjambment can also provide for rhymes. One example is Willard Espy's poem, "The Unrhymable Word: Orange".

The four eng-

ineers

Wore orange

brassieres.

I like that there are female engineers. That's progressive. Or... no, am I unprogressive for putting it that way? 

Another example by Tom Lehrer relies on the /ˈɑrəndʒ/ pronunciation commonly used on the East Coast of the United States:

Eating an orange

While making love

Makes for bizarre enj-

oyment thereof.

Rapper Eminem is noted for his ability to bend words so that they rhyme.^[31] In his song "Business" from the album The Eminem Show, he makes use of such word-bending to rhyme "orange":

Set to blow college dorm rooms doors off the hinges,

Oranges, peach, pears, plums, syringes,

VROOM VROOM! Yeah, here I come, I'm inches,

Nonce words are sometimes contrived to rhyme with "orange". Composers Charles Fox and Norman Gimbel wrote the song "Oranges Poranges" to be sung by the Witchiepoo character on the television programme H.R. Pufnstuf.

Oranges poranges, who says,

oranges poranges, who says,

oranges poranges, who says

there ain't no rhyme for oranges?
