The BBC have run a fairly good series over the last few years called "Walking with Dinosaurs" which did well enough to spin off a couple of follow-ups.
During last week it was my misfortune to commute up to London and back during the rush hour for a couple of days and the horrendous behaviour of the regular commuters when the train pulled into the station has given me the idea for one more series in the set.
The last one was entitled "Walking with Cavemen" and I would like to propose that this be rounded out by "Walking with Businessmen"...
