Footballer Francesco Totti, captain of Roma, star of the Italian national team and butt of innumerable jokes based on his alleged lack of brain power, is enjoying the last laugh. His book, "Tutte le barzellette su Totti. Raccolte da me" ("All the jokes about Totti. Collected by me") sold 75,000 copies in its first week and is riding high in the bestseller lists. Published by Mondadori with introductions by Rome's mayor Walter Veltroni, TV chat-show host Maurizio Costanzo and president of Unicef-Italia Giovanni Micali, the book costs 9 and proceeds go to Unicef and to the city council's helpline services. One example of the contents: Totti is trying to finish a puzzle. It takes him nearly four months. Then he turns the box round and reads "from 2-3 years". He says "I must be a genius!".
