Actually…

This might not be as far-fetched as Mr. McPherson thinks: when we were house-hunting some years back we came across a house whose fan, while not quite as large as this one, was powerful enough that it literally knocked my wife off her feet. The sort of thing you’d expect in a factory or something.

I don’t want to think about what the electric bill must have been for that house, but I’m pretty sure they never had to dust anything.
