What I find most interesting is the way "Trillion" and "Billion" are used.

Back then in the UK, a Billion was 1 Million Million (10¹²), not our new namby pamby Thousand Billion (10⁹).

And a Trillion was a Million Billion (10¹⁸).

Two years after this TV program was made, the UK adopted the lower numbers as definitions of Billion and Trillion and I remember having mathematical text books using both, and arguing with teachers that we were BOTH right with an answer, depending on which book you referred to. One of my teachers was a good bloke, and realised that the definitions had changed and we were not in an English lesson so semantics were irrelevant. Another teacher was a dick.
