The phaonmneal pweor of the hmuan mnid

A friend sent me the following text recently. It highlights a few things for me. Firstly, it's definitely a good idea to have spell check turned on at all times and secondly, I can now see why it's so easy for spammers to side-step unsophisticated anti-spam filters and still ensure their invitation for 'pneile elnargmenet' is understandable for the recipient. Food for thought...

“The phaonmneal pweor of the hmuan mnid -- aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoatnt tihng is taht the frist and lsat ltteer be in the rghit pclae.
