One was a British sitcom, Mind Your Language; and the other was a Nigerian version of it, Second Chance where Madam Kofo held sway! Both sitcoms were staged in a classroom of an average teacher trying to blend in semi-average students of different cultural backgrounds or countries (for the British version) and ethnicities (for the Nigerian version) to have an understanding of the English Language! It was fun those days on NTA 2 Channel 5, rib-cracking display by the various actors were must see
