OK, found out the phone box thing:

All through the series, people mysteriously fall asleep in public phone boxes. Have they fallen prey to a disease or am I carrying out some trick of the mind on the other end of the line? There are two factors at work here.
First, the group of people subjected to the stunt are particularly suggestible. I know this simply because they chose to answer a public phone that happened to be ringing as they walked past. Most people would ignore it, assuming it was nothing to do with them.
Secondly, once the person answers, I immediately bombard them with a rapid set of confusing instructions and facts. I do this for several minutes without giving give them a break, then follow it by telling them to fall asleep. As seen on the shows, this works.
Public speakers often capitalise on the same response. Have you ever listened to a politician giving rapid-fire statistics so fast that the audience can't possibly take them in, only to end the speech with a simple, memorable phrase? The soundbite comes as such a relief after all those facts and figures that this is all the listeners remember.
