So, [Karen Gillan is set to be the 11th Doctor's first companion](http://news.bbc.co.uk/1/hi/entertainment/8073734.stm).
My initial reaction was a pleasingly blokey "Cool. A cute redhead." I like cute redheads. (I cite my wife as evidence.)
And the second was "Oh, my God. She's 21. I'm old enough to be her father."
Nothing makes you feel old like the TV show you used to love as a kid…
