And it just doesn't work properly. And my fourth example is there are some cases where you really want to be - In case you're wondering, that's me at the G20 protest. I wasn't actually at the G20 protest, but I had a meeting at a bank on the day of the G20 protest, and I got an email from the bank saying please don't wear a suit, because it'll inflame the protesters. I look pretty good in a suit, frankly, so you can see why it would drive them into an anti-capitalist frenzy. (Laughter) So I thought, well, look. If I don't want to inflame the protesters, the obvious thing to do is go dressed as a protester. So I went dressed completely in black, you know, with a black balaclava, I had black gloves on, but I've taken them off to sign the visitor's book. (Laughter) I'm wearing black trousers, black boots, I'm dressed completely in black. I go into the bank at 10 o'clock, go, "Hi, I'm Dave Birch, I've got a 3 o'clock with so and so there." Sure. They sign me in. There's my visitor's badge. (Laughter)
