No, McGrath, I'm really not sure he was mocking Fox. And I think if you were to look at the video again with these things in mind...

1. Most of America was not able to see the Fox ad -- it was local. Rush's audience is national. So when he was describing Fox's spasms, he was demonstrating what he meant for the webcam to people who had not seen Fox's ad, and assumed, as Rush did, that the level of his Parkinson's was the level that most of us see every week on "Boston Legal".

2. Rush never said "faking". He purposely said "acting" and added "or off his meds". This is because most of America has been watching MJFox making regular appearances on TV's "Boston Legal". On that program, Fox shows little of the symptoms he's demonstrating in the ad. Even though I have seen MJFox having spasms, I've never seen his spasms as profound as they were during the ad.

3. There probably isn't 1 person in ten thousand familiar enough with how Parkinson's meds work. It is not at all unreasonable to assume that the case would be as it usually is with medication, that is .... On medication=symptoms subside; Off medication=symptoms increase.

Rush may be a pecker-head. But don't you just hate it when, the ONE time you yell at your kid for getting into the cookie jar is the ONE time the your kid was NOT in the cookie jar?
