Classic Limbaugh, from 2006, as reported by the Washington Post:
To Rush Limbaugh on Monday, Michael J. Fox looked like a faker. The actor, who suffers from Parkinson’s disease, has done a series of political ads supporting candidates who favor stem cell research, including Maryland Democrat Ben Cardin, who is running against Republican Michael Steele for the Senate seat being vacated by Paul Sarbanes.
"He is exaggerating the effects of the disease," Limbaugh told listeners. "He’s moving all around and shaking and it’s purely an act… . This is really shameless of Michael J. Fox. Either he didn’t take his medication or he’s acting."
As John Gruber points out, Limbaugh clearly didn’t mean to apologize, as he did an almost-immediate about-face: “I stand by what I said. I take back none of what I said. I wouldn’t rephrase it any differently. It is what I believe; it is what I think. It is what I have found to be true.”
