The OS-tan is an Internet phenomenon or meme that originated within the Japanese Futaba Channel. The OS-tan are the moe anthropomorphism/personification of several operating systems by various amateur Japanese artists. The OS-tan are typically depicted as women, with the OS-tan representative of Microsoft Windows operating systems usually depicted as sisters of varying ages.
Though initially appearing only in fan work, the OS-tans proved popular enough that Microsoft branches in Singapore and Taiwan used the OS-tan concept as the basis for ad campaigns for Internet Explorer and Microsoft Silverlight, respectively.
The concept of the OS-tan is reported to have begun as a personification of the common perception of Windows Me as unstable and prone to frequent crashes. Discussions on Futaba Channel likened this to the stereotype of a fickle, troublesome girl and as this personification expanded Me-tan was created and followed by the other characters. One of the early works to predominantly feature the OS-tan was an interactive Flash animation showing a possible intro to an imaginary anime show known as Trouble Windows. A fansub of this was eventually created and is partly responsible for the spread of the OS-tan to English language imageboards.
Well I don't know why I came here tonight
I've got a feeling that something ain't right
I'm so scared in case I fall off my chair
And I don't know how I'll get down the stairs
Well it's clowns to the left of me, jokers to the right
Here I am stuck in the middle with you
Yes I'm stuck in the middle with you
And I'm wondering what it is I should do
It's so hard to keep this smile on my face
When I'm going all over the place
Clowns to the left of me, jokers to the right
Here I am stuck in the middle with you
When you started off with nothing
And you're proud that you're a self-made man
And your family comes all crawling
Slaps you on the back and saying
Please, please
(Repeat)
Trying to make some sense of it all
But I can see it makes no sense at all
Is it cool to go to sleep on the floor
I don't think I can take anymore
Well, clowns to the left of me, jokers to the right
Here I am stuck in the middle with you
Ooh, stuck in the middle with you
Yeah, stuck in the middle with you
Here I am stuck in the middle with you
Here I am stuck in the middle with you
Yes I am stuck in the middle with you
Yeah, stuck in the middle with you
