Nelson Mandela is sitting at home watching TV and drinking a beer when he hears a knock at the door. When he opens it, he is confronted by a little Chinese man, clutching a clipboard and yelling, "You Sign! You sign!"
Behind him is an enormous truck full of car exhausts. Nelson is standing there in complete amazement, when the Chinese man starts to yell louder, "You Sign! You sign!"
Nelson says to him, "I’m afraid, you've obviously got the wrong man", and shuts the door.
The next day he hears a knock at the door again. When he opens it, the little Chinese man is back with a huge truck of brake pads. He thrusts his clipboard under Nelson's nose, yelling, "You sign! You sign!"
Mr Mandela is getting a bit annoyed by now, so he says again "Please, go away! You've got the wrong man, I don't want car parts!" Then he shuts the door again
The following day, Nelson is resting, and late in the afternoon, he hears a knock on the door again. On opening the door, there is the same little Chinese man thrusting a clipboard under his nose, shouting, "You sign! You sign!"
Behind him are TWO very large trucks full of car parts. This time Nelson exasperated says "Look, I don't want these! Do you understand? You must have the wrong name! Who do you want to give these to?" The little guy looks very puzzled, consults his clipboard, and says:
(Wait for it, it's a beauty)
(Get your best Chinese accent ready)
"You not Nissan Main Dealer?"
