CoD4: Aftermath level Easter Egg. [spoilers]

[Fish]

 So I know any who has played through single player can remember the Aftermath mission.
I just recently found out about the easter egg of the children's laughter and the little girl saying "Daddy, I love you." if you survive long enough in the school yard.
I can't seem to live long enough to hear it. D= I can get to the school yard and hear the children, but the only the that sounds like a little girl is a "No!" when you fall down.

Anyone know how to hear it?

Stand up in the HELICHOPTER helps but if you can make it out of the HELICHOPTER before it gets full red outside you've got it in the bag.

I actually didn't know what that girl said thanks for the help
