Sorry to be pedantic but the latest FB post has put me over the edge.
SU apparently have a new Phone Box stamp and the trend is to color it blue and call it a Police Box or TARDIS from Dr Who. They are two completely different things. A bit like calling the Gateway Arch the Washington Monument and saying it doesn't matter.
I'm positive Whovians will appreciate the effort, but they will also know the difference between a Phone Box (which is normally only red) and a Police Box.
