Problem with load event

[Hubbitus]

I have simple document:

<script>
$(document).load(function(){
alert('Document loaded')}
);

$(document).ready(function(){
alert('Document ready')}
);

$(document).live('load', function(){
alert('Document loaded (live)')}
);
</script>

But from 3 attached events on page load fired only one -
$(document).ready. I even can't imagine why :( .

I've tested it in FireFox 3.6 and Google Chrome 5.0.322.2 dev.
Any sugestion?
