The world's oldest recorded joke has been traced back to 1900 BC and suggests toilet humor was as popular with the ancients as it is today. It is a saying of the Sumerians, who lived in what is now southern Iraq and goes:
"Something which has never occurred since time immemorial; a young woman did not fart in her husband's lap."
"Something which has never occurred since time immemorial; a young woman did not fart in her husband's lap."
