I've just spent what seems forever travelling around xkcd's latest comic, aptly titled click and drag, deciding to explore a cave to see if I could find something clever hidden away (and that I did find, like the X-Wing, a hidden lake and some other references I have completely missed). In the process, after emerging who knows where, crossing a sea, passing by a rocket on a launch-pad I reached ONE end of what must be the biggest comic ever created. Very clever although I have absolutely no idea where I am now -- which may be the point of his analogy.
