I thought I'd share this little experience with you guys.
When the 2000 Olympics were on, a company called 'Visyboard' sponsored Muhammed Ali's visit to Australia. As part of the deal, Ali went around to the 'Visyboard' factories and met the staff, interested passers-by etc.
Anyway, the Carole Park factory is just down the road from where I work, but I really couldn't make the time to see him. I was out all morning, and got back around lunchtime. As I was driving up the street, I saw a big limousine coming the other way. The limo stopped to let me pass before it turned into the Visy factory. Although the windows were tinted, as I drove past, I could clearly make out the face of the great Muhammed Ali in the back.
Taking all the above things into account, I can truthfully say that I'm one of the few people who have 'stopped' Ali!

groan! Nice story and pun .. you should get your ears boxed just for that.
