Stupid, apparently.

I thoroughtly recommend that you read this rather good speech of President Bush's:

Most of you probably didn't know that I have a new book out. Some guy put together a collection of my wit and wisdom — or, as he calls it, my accidental wit and wisdom. But I'm kind of proud that my words are already in book form. So like other authors, I thought I'd read from it tonight. It's like the thoughts of Chairman Mao, only with laughs, and not in Chinese.

....

Now, most people would say, in speaking of the economy, we ought to make the pie bigger. I, however, am on record saying, "We ought to make the pie higher." It is a very complicated economic point I was making there. But believe me, what this country needs is taller pie.

....

Then there is my most famous statement: "Rarely is the question asked, is our children learning." Let us analyze that sentence for a moment. If you're a stickler, you probably think the singular verb "is" should have been the plural "are." But if you read it closely, you'll see I'm using the intransitive plural subjunctive tense. So the word "is" are correct.
