HTTP status cats by GirlieMac: classic server error codes, now with cats

GirlieMac, aka Tomomi Imura (Twitter) just won the internet with her deftly conceived and Photoshopped series of HTTP status message "motivational poster" images, featuring cats. A bunch of them are featured above and below. The full set is here at Flickr. She's taking suggestions for more, if you can think of any she missed. (thanks, Bonnie Burton)
