SPEECH MAY BE SLURRED, BUT ALI'S STILL ON HIS TOES

Muhammad Ali's speech has been slurred by Parkinson's disease, but his sense of humor is intact.

Although the former boxer refused to speak on camera for a "60 Minutes" profile that will be broadcast on Sunday, he and his wife, Lonnie, played a prank on correspondent Ed Bradley during an on-camera segment.Ali, seated at a table with his wife and Bradley, gazed vacantly into space while his wife explained that the champ occasionally lapses into the trancelike state - and sometimes even throws punches in the air.

At that point, Ali threw a left hook toward Bradley's head.

Bradley warily moved away; Ali smirked and those at the table broke into laughter.

"You got me," Bradley said.
