Because when he was young, he had acted in a film named "Jyoti the Dragon"...After he got old, Bruce Lee took over from him.
Its since that time, Jyoti the Dragon carries a bottle of black label scotch whisky and two cut glasses in a special leather case. He never misses a sundown drink. If you dont believe it, ask him and he will tell you.
If you tell him that scotch is a rich mans drink, he will reply: "Young in man in your system of government, only a few rich men can enjoy scotch. In our communist system, we want that everyone should enjoy scotch". And then he will burst out laughing.
