Italians like speaking a lot. They say what they think and feel as often they can, and as loud as they can. They express emotions pretty much every moment, they are awake.

And who would demonstrate that better than our jolly politicians:

Beppe Grillo from the "Movimento 5 stelle", an oppositional party to everything, tells them: "I'm gonna take you down!"*
