One of my two greatest sports heros. Not a perfect man, but who is? On the whole, I'd say he's led a good life and made a positive difference in the world, and in the end I think that's all you can ask of anyone. Greatest fighter of all time, in more ways than one. Happy birthday, champ. Always the greatest in my book.

I thought he would lose to Sonny Liston....he didn't. I thought he would lose to Joe Frazier...he didn't. I thought he would lose to Ken Norton...he didn't. I thought he would lose to George Foreman...he didn't. I thought he would lose to Larry Holmes...he didn't. He was the greatest fighter to ever step in to the ring.

One of the greatest athletes and champions of the 20th century. Happy Birthday champ!

that's Maine, not Miane...harumph.

Anyway, Ali has always been the man. I remember my little, tiny mother screaming for him when he was fighting on tv in black and white. She *never* screamed. He has always been the most entertaining sports figure ever, bar none. You da man, Ali!!!

I used to listen on the radio to his first fights as Cassius Clay, but he'll always be Muhammad Ali to me. Happy Birthday.

Mr. Ali. How does someone wish you a very Happy Birthday. I rweally wish I had some clever way of doing it , but I dont. I did the chance to meet you several years ago . It was a true honor and privilege to be able to. You were very gracious even with hundreds still in line to get your autograph, You took the time to talk for a minute and shake my hand. It was something I will never forget. You have been an inspiration to millions, me being one of them. Thank you. My family and I would like to extend a sincere wish for many...many more wonderful birthday. HAPPY BIRTHDAY CHAMP!!

A fine and popular boxer in his day. But I reserve the accolade of "The Greatest" for those who helped defend their country.
