Here's why:
* Unusual Number: It's a very specific number, not a common word with multiple rhymes.
* Multiple Syllables: The phrase has multiple syllables, making it harder to find words with matching sounds.
However, you could explore near rhymes or slant rhymes that share some similar sounds:
* Near Rhymes: "twelve", "helve", "delve" (share similar vowel sounds)
* Slant Rhymes: "twelfth", "twelve-month", "shelve" (share some consonant sounds)
Ultimately, finding a perfect rhyme for "two thousand and twelve" is a bit of a challenge!
