So here's the thing.
In this week's episode of Doctor Who, we had a definitive answer to the vexed question of dating the UNIT years. When encountering the modern UNIT operation, the Doctor explained that he used to work for them:
"Back in the 70s. Or was it the 80s?"
It's times like this, when not only do I pick up on in-jokes like this, but I actually laugh out loud at them, that I realise I'm a bit of a geek. And of course, the logical thing to then do is draw attention to this by writing about it in my blog, so that everyone can know just what a geek I am.
