I think it's called WITCH GIRL GET PIE IN THE FACE.

You positive about that?
I'm fairly certain it's called "Japanese Girl Take Pie In The Face."

C'mon, Rich, don't tell me you've never watched WITCH GIRL GET PIE IN FACE! Not even after Meryl Streep won the Emmy as Witch Girl's mom?

It's from a Jpop music video...I can't remember whose...
There really isn't much more to it thank you see here, although there are clearer versions floating around the net.

This clip is from Japanese TV show "Channel-a" broadcast in 2006.
It showed the making process of the music video of "VS" by Misono, Japanese singer.

As for the music video, you can see on Dailymotion.
