When someone dies or falling to their death, mmm what she say.?

If anyone watches funny stuff on Youtube. When someone dies, or falling to their deaths, a song plays. It goes something like mmm what she saaayaaay. I don't know if its something like keyboard cat or what. Someone help me out? Examples include that death note spoof from saturday night live, Outlaw Star abridged ep 4. Look'em up your self to see with your own eyes.
