I linked to a post from another wordpress blog. After I linked, the person password protected that post and wrote a satire on my blog. So I posted about it and linked to the now password-protected post. When I hover over the new link, I see a cached version of it in the Snap Preview feature, with the content still there, instead of the password protected page.
The post was obviously cached - how can I get at it?
The links in question are in the first post on my blog if you want to take a look.
