Oh... I got into a mysterious row with the other half (and he wasn't even drunk) about Doctor Who.
First of all he was convinced that the Type 40 was clearly stated to be the most common Tardis type when it clearly wasn't and then I suggested that the population of Gallifrey would be significantly higher than that of Earth based on the number of children the Doctor 'killed".
2.47 billion is roughly the number of children on Earth but the population lives significantly longer (roughly 5 million Earth children don't make it to their first year). If that is an indication of the number of children on the planet at any given time and the population hasn't gone up or down because of the war that would in estimation make the population much bigger than ours.
Which is okay because the planet is bigger and they could build dimensionally transcendental cities but he insisted the population was lower or the same.
He is now sulking upstairs.
PS I just logged onto Gmail and found he had continued the argument via email from his bedroom...the geek has inherited the Earth.
