Zimbabwean joke

Fatso was rushing for an important meeting and afta a few km he had a flat tyre. When he was changing the wheel all the nuts fell into the drain. He bcame so frustrated and didn't know what to do. He just sat down besides the car akabata shaya apererwa. Suddenly a mad man appeared and said to him, "hey man you look so frustrated what happened?" Fatso just looked at him and kept quiet. The mad man asked again, "what happened man?" Fatso decided to answer and said , "I lost all my wheel nuts in the drain and I was rushing to an important meeting, now I dont know what to do". The mad man smilled and said, "why dont you just remove one nut from each of the three wheels and use those so you can rush to your meeting." Fatso smiled and said, "aahh, never thought abt it." After he was done he asked the man, "sir you seem to be a mad man but you gave me such a brilliant idea, how is that so? The mad man smiled and said, "Kupenga nekupusa zvakasiyana mface wangu" THERE'S A DIFFERENCE BETWEEN BEING MAD AND BEING STUPID.
