Girls gettin pied nicely starting at 1 hour 22 minutes. At the beginning of the show there's another game involving flour, but not that great.

Good find. I know it's a long shot, but do you know if the blonde host during the pie segment has ever been pied?

Like most brazilian hostess of this kind of shows... the answer is NO!
At least not in all the clips I saw from the show, and I saw lots of them.
