We have a "little man" in at work today taking down a partition
between two offices.

The "wall" consisted of metal studs, with plasterboard for the bottom
metre or so, and double glazed units above.

Guess which he took out first.

I'd just said to a cow-orker "I don't think he ought to do that" when
there was an almighty crash and a slight enlargement in the number of
pieces of glass.
