Love the episode and Matt Smith made me laugh. He is genuinely brilliant.Oh please. He didn't say he didn't know what football was, he asked to be reminded which one it was. Don't you think 'knowing everything about everything' makes picking out specific bits of everything less than straightforward? You know, as evidenced by the Doctor's behaviour, oh, every week? And which part of his UNIT-years exile involved him living as 'a normal bloke' anyway? Out for a pint with the lads? A kickabout with the Brig? Back to the bachelor's pad with a tie hanging around Benton's door?
And anyway, comedy doesn't let facts get in the way.
Plus, he is old, perhaps he is getting senile lol
That is how i took it, the Doctor is just getting old, he has a LOT to remember, and things get jumbled up sometimes, he can't recall everything in the right order cause his life is so out of order all the time haha
As for the comments about the Doctor not knowing how to act like a proper bloke, know what football is, and all that I just chalk it up to both his being eccentric and post-Regeneration recovery. He's also been having other issues with remembering things which makes me think that his erratic behavior/lack of memory is due to the Crack.
