LOLCATS best-of (and they're all best btw) compilation video here. A lot of people complained that the frames changed too quickly, but I think this was a great conceptual move on the creator's part. The frames started out slow and towards the end went by so fast, you barely have time to finish reading. If you actually need more time to read everything, you have to keep pausing the video. The point being that this brand of humor is highly edible and addictive. And millions love it.
After you watch several dozen, the LOLcats slang grows on you. Words that you never knew existed suddenly seem so right: caturday, harbls, meh, eated, etc. And the random pluralization of anything makes it funnier. This suddenly reminded me of another kind of less savory humor, which made me feel a little bad for loving LOLcats. The kinds of ads that infantilized African-American characters/spokespeople in the early 20th century used the exact same comedy tactics. Are we creating glaringly inappropriate stereotypes of cats? Is LOLcats racist? Probably not. Sometimes a cheezburger is just a cheezburger.
