I actually wanted to submit this version, with only the hot women singing the song, which, of course, is much better suited for Berlusconis' persona:

I just wasn't able to find it until just now

Awesome. Excruciating. [Easier to look at]. Ridiculous lip-synching, especially the second woman at the fruit stand in 0:24, where the singer's belting it out but the actress is just standing there.
Of course to represent the totality of Berlusconi media they should have been news presenters with their tits out disparaging dissent.

There's a parody version on youtube but you have to know Italian.

Sì possiamo!

Menomale che Obama c'e!

I had that typed up before I remembered you're Romanian and will not erase it.
