"Oh, oh, and you know what else I found on the web? It's these pictures of cats and they write these — Oh, look at this one. "Invisible cheeseburger!" No, huh? Well, it's not for everyone. I just think they're funny."Lolcats are are an internet meme which is best described as the lovechild of Cute Kittens and Memetic Mutation. Lolcats are Image Macros that combine photos of cats with humorous captions, usually in a form of broken english known as "kitty pidgin" or "lolspeak." It should be noted that using bad spelling as humour is hardly a new phenomenon. And the practice of combining cats with funny captions◊, goes back even further. However, the modern-day phenomenon of Lolcats originates from the Image Board 4chan, where every Saturday users posted funny pictures of kitties, a practice called "Caturday". This didn't become a sensation until the launching of the website I Can Has Cheezburger?, which takes its name from this popular image.However, the Lolcat phenomenon extends further than just Image Macros. It also spawned "Kitty Pidgin" (a.k.a "Lolspeak"), which is widely regarded as being "the first language born of teh intertubes", along with a programming language and even a kitty theology, complete with its own Bible translation and blasphemers. Just don't do it in real life. There's been an article on them in Time magazine.They have spawned spinoffs like Loldogs, Lolruses, Lolbunnies, Lolbirds, Lolhamsters, Lolowls, Lolpigs, Lolthulhu, and even Lolhumans like Lolpresidents.
