If you knock out a hunger (player->sethandtohand 200 if you want to test that quickly), it starts glitching out horribly. Apparently it emits a sound (probably the land/body fall sound) every single frame, resulting in an ear-splitting horror. I think to fix that (if I'm not mistaken on the cause), one has to edit the animation frames, but I'm not really sure about it.

Edit: if you look at the Hunger's animation window in the CS, you see that the Knock Out animation has a loop start and loop stop both at frame 264, so it loops that frame constantly. And that frame does play the Body Fall Large sound. (Which is redundant since it's also played in frame 260, that ought to suffice.)
