It is incredible how an intelligent person's mind can go blank when you have three cameras stuck up your nose and no script. And we can't legislate for the weather. One rainy day I was up on the top deck doing my thing with my colleagues dancing around behind me. We were getting a good reaction, which tailed off a little when it started to hail, but I carried on. When I looked round to see if the others were enjoying it as much as I was, I found they had all disappeared downstairs.
Somebody also has to stand at the front and look out for low-flying trees.
Ken is actually the best. There are remarkably few hostile reactions to the bus, but it does happen. One immaculately dressed middle-aged woman made a gesture I haven't seen since school. I'm most baffled by people who try to pretend the bus isn't there. They can see us, we know they can see us, but they keep walking, looking neither right nor left as though there is nothing unusual happening.
