I think the time (and relative dimensions in space) has come to say a happy birthday - a happy fiftieth birthday - to a rather special person. Or persons. There's sort of twelve and a half of them or something. And we think they're rather awesome for saving time and space a few bajillion times.
Here's to adventures in time and space, wherever they may lead us.Here's to companions found and lost, past, present, and future.
And here's to the Doctor, for all his sterling work over the last fifty years.
Enjoy the anniversary, everyone! Let's go save the day!
