There is partial truth to that rumor. The president did say I would be good in the role, but when he said that, he didn't know I'd already been cast. His approval wasn't needed -- I'd already been selected by Steve Martin.

When an uninstructed multitude attempts to see with its eyes, it is exceedingly apt to be deceived. When, however, it forms its judgment, as it usually does, on the intuitions of its great and warm heart, the conclusions thus attained are often so profound and so unerring as to possess the character of truth supernaturally revealed.

I don't care what the rumor mill says. That's the truth.

There is no truth to that rumor.

I'm afraid that was just a rumor. No truth in it,

The cold hard truth will fall on stony ground, whereas your all-around trashy rumor will flourish like a weed.
