During the colonial period, some Ibadan Chiefs went to a meeting with Mr Hezekiah Shunklebottom, the notoriously difficult British district officer.
In the course of the meeting the district officer was happy with what the Ibadan chiefs had to report and present
via an interpreter. He kept nodding and saying “good good good good good good good yeah yeah yeah yeah yeah yeah.”
One of the chiefs counted the “good” which turned to be 7 and the “Yeah” which was counted as 6.
… And so when they got back to Ibadan they reported to Ibadan folks that the “Òyìnbó ṣe gudu gudu méje àti yàyà mẹ́fà”.
