I don't think I see the world in terms of stupid or clever, but in terms of being able to get irony. There's some awful statistic about only 20 per cent of Americans being able to understand irony.

I get verklempt if I see a vintage TI-30 or TI-54 calculator. But I don't think I'd want to use one.

I'm a visual thinker. Research tells us that only 20 per cent of people think visually. So what about the other 80 per cent? Don't they think in pictures? I mean if you imagine washing and preparing potatoes you visualise the process, right?

If I think too much about all of those Chinese factories where all the stuff in a Wal-Mart is made, I get that woozy feeling you get when you see ducks covered in crude oil.

I grew up in airports and on air bases. I know what flying and airports can be. And most airports make me feel like we're about three per cent better than ants. Especially U.S. airports. They're zoos. All civility is gone.

Every human being you see in the course of a day has a problem that's sucking up at least 70 percent of his or her radar.
