Looking for "K.O" notification sound

[MyNamesTooLong]

The one from the scott pilgrim movie...It seems that the movie may have sampled street fighter alpha 2 or 3's K.O and added an echo. Can anyone help me out with either, or both?

I dl'd a youtube vid ripped the audio and cut out everything, but the ko, but the quality isn't what I wanted...
