In London people use humor all the time. It's more a case that in London people are always ready to be to make fools of themselves or to use self-effacing humor. In France it seems that when someone tells you a joke they kind of slap the knee and show everyone that this is a jokeyou know whereas in England because humor is always there to an extent the delivery of a joke might be less obvious. I'm sure we'll leave that up to the sociologists and the cultural theorists and things about exactly what uh English humor really means.
