Looking for a campaign with mixed-up letters. Who can help?

Hey folks,

some time ago, there was this mildly interesting thing going through the web, where in a paragraph all the letters were completely mixed up, except the first and last of every word. Usually there was this example:

Aoccdrnig to rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit a porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.

And if I remember correctly someone used this for an ad-campaign later. But I have no idea what it was for and who made it.
if it does exist, I'd like to include it in a presentation, so I'm looking for it all over the internet. So far I found nothing, so I thought, maybe you can help me, since this seems to be the biggest advertising knowlege base on the web.

So, any idea? Thanks.
