You win people's loyalty through their stomaches, so you could start world domination through the food supply. You could use buses to distribute breakfast across the whole world - they could be "Unversal Cereal Buses"...
I just watched this episode again and I'm sure that Stephen Fry got the bus driver's name wrong.
I heard him say "Albert Gunton" when in fact the driver's name was "Albert Gunter".
Or did my ears deceive me?
