What's the worst typo you have ever made, received or come across?

[Cyclops]

I asked a good friend to proof check a local history book I wrote. I included him in the credits.

It was only after I had sent out hundreds of books that someone pointed out that I had written "...and grateful thanks to Alan ........... for poof-reading the m****cript'

Another typo that appear in a newspaper hangs round my neck like an albatross. I lived in the Midlands for ten years and handled the press releases every quarter for a big organisation. I was also a keen cyclist and on the day of publication, I rode round Salop picking up the newspapers to collect the releases that made it into print. I digress. One write-up followed a particularly important event. Instead of writing that it was a 'milestone in company history', the West Midlands was informed of the company's 'millstone'.
