I’ve seen umpteen variations on this in images, mostly on LiveJournal… I am assuming that it is a parody of something but I don’t know what. Help?
Oooh, I just learned this last week, it’s from an online game and was originally “I am in your base killing your d00ds”. Here’s the story from Encyclopedia Dramatica:
Just a weird internet meme like “all your bases belong to us”. Here’s my favorite knock-off.
Someone had a cat blog with daily submissions. After a while, people starting captioning them in broken English.
Can’t find the blog right now, though.
When do we see the first bumper sticker. . .
I’m in ur lane, blocking ur vi3wZ
It all makes sense now! 
I’d love to find that again, or copies of the pictures in jpeg format. I want to send them to my daughter (away at school), one a day, just for laughs. Any one know where to find them or have copies of them?
There was a really cute one that said, “I made you a cookie, but I eated it” that she liked.
There’s even a website for it now:
Some of the captions are whooshing me though. Guess I’m gittin’ old…
Wow, it doesn’t take much, does it? I hope I don’t inadvertently create an Internet meme.
There are a lot of those on this site. The cookie one is there, you just have to scroll down a ways…
What is this “harbl?”
Hairball.
Yep, thanks, tremorviolet. Got it from that one and the one Dante posted. Funny pictures.

Ahhhhhhh! Thanks. Heh, I thought it was a body part.
I think my favorite was posted right after the recent election. I can’t find it now, but it shows a cat on a podium with the congressional seal, saying “I’m in ur house, stealin ur seatz”
I love this thread!
(I am so easily amused. It’s sad, really.)
