First listen and then answer the question.
What was the joke?

    'To end our special news bulletin,' said the voice of the television announcer, 'we're going over to the macaroni fields of Calabria. Macaroni has been grown in this area for over six hundred years. Two of the leading growers, Giuseppe Moldova and Riccardo Brabante, tell me that they have been expecting a splendid crop this year and harvesting has begun earlier than usual. Here you can see two workers who, between them, have just finished cutting three cartloads of golden brown macaroni stalks. The whole village has been working day and night gathering and threshing this year's crop before the September rains. On the right, you can see Mrs. Brabante herself. She has been helping her husband for thirty years now. Mrs. Brabante is talking to the manager of the local factory where the crop is processed. This last scene shows you what will happen at the end of the harvest: the famous Calabrian macaroni-eating competition! Signor Fratelli, the present champion, has won it every year since 1991. And that ends our special bulletin for today, Thursday, April lst. We're now going back to the studio.'
