I know Peter already did this one, but a different answer came to me:

How many British Spins does it take to change a lightbulb?

So, as I predicted in my previous post, the lightbulb burned out a few hours ago. The question now has to be, what will Tony Blair and Alastair Campbell do to replace it? (One could, of course, ask what Iain Duncan Smith would do to replace it, but as he'll never be in a position to do so, it's safe to ignore him and talk about teeth instead.) My prediction? The bulb will be replaced with another bulb.
