Since we are into "same on two days" etc., here is a neat result (VERY non-tri-
vial!)  It's (an application of) the Borsok[sp?]-Ulam Theorem:

At any given time, there is a pair of points A,B on the surface of the earth
with the property that:

	1.  A and B are antipodal (the line joining them goes through the center
		of the earth;
	2.  The temperatures at A and B are the same;
	3.  The barometric pressures at A and B are the same.

(You can substitute any continuous, everywhere-defined functions of 2-d location
on the surface of the earth for temperature and barometric pressure.)
