A Japanese traveller wanted to visit India. He reached the airport & hailed a taxi. The taxt driver was from Calcutta. The Japanese said: Your taxi goes very slow. Japanese taxi goes very fast. Your buses are very slow. Japanese buses are very fast. 'What!!!!' yelled the Japanese at the end of the journey, 'your meter goes very fast!' 'Yes, sir', said the taxi driver, 'it is made in Japan!'
