How to find the top frame?

How would I find the most top frame on a page using javascript? For example, someone iframes my site within another iframe. I want to know the upper most frame's URL. How would I do that? Thanks.

try
top.frames[0]

I get [object Window] or [object] as the variable. I need to find the URL of the topframe. My current code is as follows...

var TopFrame = (document.top == document.self);
if (!TopFrame)
{
TopFrame = true;
}
else
{
TopFrame = top.frames[0];
}
