>At the last summer Olympics someone from Golden Palace tackled a runner, at this Olympics a guy grabbed the mike from one of the dignitaries during the closing ceremonies. He said something in Italian, I think.

From AP Wire service:
The man approached the microphone during a speech by organizing committee chief Valentino Castellani and shouted, "Passion lives in Torino," the slogan of the games.

In a separate incident at the start of the ceremony, a female streaker tried to run onto the stage but was turned back by security.

I kinda wish they had done it t'other way round!
