Having fun, Phage, haven't you ? :-)
Ok so let's exercize further: what about horizon ? The Earth must be at least curved...all the way "round". With a very clear sky, on the sea for
exemple, you can see boats "falling" in the horizon, but we know they do not fall (at least not before reaching the rim of our Discworld!) as they
generally reach their final destination (unless they go in the Bermuda Triangle, of course, where they are sure to be abducted by Aliens, or drawn in
the ocean's deth by some mystical crystal pyramid, or whatever). So there must be a curve. And this is the case anywhere in the world, so the curve
must be continuous.
How about that? (and I'm sure you will find an answer to that too)
