It's behind you!

Knock Knock
Who's there?
Doctor
Doctor Who?
You just said it!

Lame joke from my youth, in the days when we'd race home from playing out in time for Doctor Who because if you missed it then you missed it, and it might be a year before it was repeated. No iPlayer, on demand, or catch up TV then.

My two boys are partying tonight so we'll watch it all together tomorrow night. Thank goodness for technological advancements. :-)
