Go click on this link.
It's a 404 page now, but it used to be the home of Apple's retail stores. Why they'd move that page is a giant mystery to me, but whatever.
Go to the bottom of that page. There's a link to click on to visit an Apple retail store. That link takes you to -- wait for it -- that same page.
I have no words.
EDIT: At some point later that week, they fixed it. It was, at the time however, yet another thing that was annoying me that particular day (the iPhone 3G launch day).
