Jawahar lal Nehru Joke

Jawahar Lal Nehru was in Moscow and was addressing a huge public gathering. As Nehru was speaking in English an interpreter was translating the speech to the crowd. Suddenly Nehru started reciting a joke. The joke was complex and lengthy. To Nehru's  surprise the interpreter translated the joke in a few words and the audience roared in laughter. 

On his way back Nehru congratulated the interpreter and asked him as to how he could translate the long joke and tell it in Russian language so very quickly. The interpreter replied " Sir, to be frank with you, I did not understand the joke. I told the audience, the Indian Prime minister has cracked a joke and it would be very nice if you all laugh at it" The reply made Nehru Ji speechless!
