Patent Cooperation Treaty!--or to think one does, and yet to know that it is equally possible to have answered every single exam question incorrectly.* However, I did correctly answer that Canada is the 2nd largest country in terms of area, unlike a gaggle of TV anchors. Ha! Small victories.
*Actually, I think I got one right. The other 19, not so sure. Fortunately, most everyone else was probably in the same boat.
