Thanks, I just figured that out last night reading Crockford's
"JavaScript: The Good Parts." I considered posting what I learned,
then realized that Mike explained it perfectly in the first reply, I
was just being dense. Thanks for the explanations!

Hi,
I'll see if I can break down the syntax for you to illustrate what's
going on:
1. Define a function. It should take one argument, called $:
function ($) {
// Do stuff.
};
2. Since the function is anonymous (it doesn't have a name), you need
to wrap it in brackets before invoking it:
I still have no idea what's going on syntactically, but now I know
what's happening. This reinforced the concept (writes "Poop!" to the
screen):
(function(poop) {
document.write(poop);
}) ("Poop!")

It's very important becuase the symbol $ is used by other javascript
libraries and it can cause a conflict if you use it outside of the anonymous
function.
For example another sloppy library might have a global definition
var $ = function(){
alert('Not Cool Man!');
};
then if you tried to use
