'The Greatest' Salutes Barack

(Photo: Splash News Online) Okay, we're all ODing on Inauguration stimulus...but this one deserves mention.

Boxing great Muhammad Ali -- who turned 67 on Saturday -- was the guest of honor last night at a party of 1,400 people celebrating the impending swearing-in of Barack Obama.

Ali will also be sitting just a few feet from the president during the ceremony.

"He wouldn't have missed this for the world," his wife Lonnie said.

The former Olympic Gold Medalist, who suffers from Parkinson's Disease, famously went from being a fighter to a pacifist when he was about to be drafted into the military in 1966, at the height of the Vietnam War.
