OK, simple:
self = $(this);
Throws a JavaScript error in IE8 when it's inside an event handler. It works in every other browser.
var self = $(this);
Throws no error. Why?

A:
The answer is that var keyword staring back out at you.
When you reference just plain self, you're referencing a global variable and IE won't let you change it. When you write var self you're declaring a local variable.

Is 'self' a reserved word in IE8, or is IE8 just weirder than every other browser regarding global JavaScript variables?

It's not a reserved word, exactly, but it's a property of the `window` object that IE won't let you alter.
