A Sukuma friend of mine from Kahama recently bought a new Toyota Premio car (automatic). He drives the car perfectly well during the day but at night the car just won't move.
He tried everything and still no luck. He then called the dealer and they sent out a technician .
Technician: "Mr. Ngosha, Are you sure you use the right gears?"
Livid with anger, Ngosha replied: "Of course I always do, how else do you think it moves during the day? I'm not stupid."
The technician asked Ngosha to tell him how he selects the gears.
Ngosha: "I use D for “day” and N for night."
The technician is still rolling on the ground laughing!
