The navigation and communications system on a plane flying over Nigeria failed and hence, the pilot couldn't know where they were. Seeing a tall building, he dove low so he could pass by the balcony, where he saw some people standing. As he passed by, he shouted 'Please, Where are we??'.. The people answered with one voice 'You're in a plane'. The pilot flew up immediately, saying nothing more, and after a while, he announced 'We are in Nothern Nigeria!'. The co-pilot asked him, 'How did you know that?', to which the pilot replied 'Where else in Nigeria can you get such stupid answers?'
