Silvio Berlusconi, the flamboyant Italian Prime Minister, played a practical joke on the German Chancellor today by jumping out at her from behind a lamppost when they met for an Italo-German summit in Trieste. Slipping away from the welcoming committee, the Italian leader hid behind the lamppost and emerged with a cry of "Cucu!" when Angela Merkel stepped out of her official car to enter the regional council headquarters where they were to meet. Reports said the German leader, who appeared amused, opened her arms and replied "Silvio!".
Bonus: There's video footage of this great moment in international diplomacy.
