Ah, I see what you're getting at. It's attaching the function to an onload event, if it were just:

function dave() {
  ... code ...
}

That by itself wouldn't do anything, just define a function. It would work just as well to do:

function dave() {
  ... code ...
}
window.onload = dave;

'
But that's not as neat. What you first posted is a good example of Javascript's support for functions as first-class objects. Simply put: functions are treated just like variables in Javascript, it's pretty good stuff.

Thanks for the reply jeeves,

something = function(){

}

rather than:

function(){

}

It looks like a function for

It looks like a function for recursing through all the links on a page, changing their onclick handlers to run the popUp function. Does that make sense? There's got to be more to it than that, anc must be defined somewhere: getElementByTagName or something like that.
