A wave swept my friends list about a week ago of linking to a site that took the headlines from blogs/journals/etc and made them into cat macros. The site picks photos based on the captions themselves (for example, notice that all blank-titled posts turn up the same image). I give my posts a wide range of titles, so the LOLFeed of my journal, here, has turned up some amusing finds.
Hard to forget (if you just look at the good ones) that these were picked out by a computer.
The overall winner** has to be the sad-looking kitten captioned :). A close second is bored kitty at Most Awesome Meme Ever.
