From the Guardian.co.uk:
Mafia clans have used a popular football show on Italian television to send secret messages to jailed godfathers held in isolation, a magistrate has revealed.
Imprisoned crime bosses were kept up to date on mob business through mobile phone texts sent to the show, Quelli Che il Calcio, which unwittingly scrolled them across the bottom of the screen, among innocent messages from supporters of Italian football teams. ...
Simona Ventura, the programme's presenter, said the show's producers had been unaware of the ruse and would stop airing texts immediately. "The show has always had universal appeal, from the young, to graduates, to the old, and now, I discover, mob bosses and their families too," she said.
So, that explains the whole Frank Caliendo thing.
