Guinness World Records dates its oldest recorded-humour example to at least 1900 BC and says it may reach back as far as 2,300 BC. Those claims make the proverb ancient, but they do not establish that this particular line is exactly 3,500 years old or definitively the oldest joke in the modern “yo mama” category.
What does the ancient saying actually say?
Guinness World Records gives the translation: “Something which has never occurred since time immemorial; a young woman did not fart in her husband’s lap.” The line is presented as a Sumerian proverb. Its comic image is a wife and husband; it does not use the modern “your mother” setup or target someone’s mother.
“Yo mama joke” is therefore a contemporary comparison that makes the ancient text easy to recognize as irreverent humor, not a literal description of its wording or form.
How old is it—and what do the dates mean?
There are several dates in circulation, and they refer to different things. Guinness World Records describes the oldest recorded-humour example in its account as dating to at least 1900 BC. The same account says the proverb may date as far back as 2,300 BC. That earlier date is a possibility reported by Guinness, not a securely established date for the surviving tablet or the exact line.

| At least 1900 BC | Guinness World Records’ dating for its oldest recorded-humour example. | A date used in Guinness’s account; it does not establish the line’s exact age. |
| Ca. 1900–1600 BC | The Cuneiform Digital Library Initiative (CDLI) gives this broad range for relevant Old Babylonian proverb tablets and records. | It situates the surviving tablet tradition in a period, rather than pinpointing when this particular saying was first composed. |
| As far back as 2,300 BC | Guinness says the joke may date this far back. | A qualified possibility, not a definite date for the quoted line or its surviving witness. |
These distinctions matter: a proverb may circulate before the copy that preserves it, and a date assigned to a group of tablets does not by itself date one particular sentence. The catalog record for CDLI Literary 000796, example 003 (P297200), identifies a Sumerian wisdom or proverb tablet from the Old Babylonian period, held in Yale’s Nies Babylonian Collection. The available catalog record does not identify that tablet as the exact witness for the quoted translation.
Is it really the world’s oldest “yo mama” joke?
That depends on what the label means. Guinness presents the example as the oldest recorded humour it discusses, while the modern “yo mama” label describes a different kind of joke: an insult built around someone’s mother. The Sumerian line is a proverb about a young woman and her husband, so the label is catchy but imprecise.
The evidence supports an ancient Sumerian proverb tradition and the broad Old Babylonian context of relevant tablets. It does not prove an absolute record across every kind of joke, establish the exact surviving tablet for this translation, or show that the line is exactly 3,500 years old. Guinness attributes its account to research led by Dr Paul McDonald, a senior lecturer at the University of Wolverhampton’s School of Humanities, Languages and Social Sciences. The page quotes McDonald as saying, “This definition enabled the team to plot the history of the joke as far back as 1900 BC.” That is Guinness’s account of the research and its dating, rather than a precise date for the proverb’s composition.

Even with the dating limits, the saying offers a small glimpse of irreverent humor in ancient Mesopotamia. Its comic force comes from an exaggerated claim about something supposedly never happening, followed by a deliberately crude image. It survives as part of a proverb tradition, not as evidence that people in ancient Sumer told jokes in exactly the same social setting or format as modern “yo mama” jokes.
For broader context, the scholarly volume Sumerian Proverbs: Glimpses of Everyday Life in Ancient Mesopotamia reconstructs a corpus from 56 partially duplicating tablets and fragments. JSTOR’s record says 45 pieces were excavated at Nippur in 1889–1900 and 11 during the 1951–1952 season. That corpus is useful background on Sumerian proverbs; its collection details do not independently verify the precise date of this particular line. Readers interested in Sumerian texts more broadly can also consult Yale University Press’s Sumerian Literary and Historical Inscriptions.
