Would you be interested in knowing that the actual length of any river is about three times longer than the straight line joining the source to the end then? That's Maths too.
Eh? That must depend on the age of the river. And the softness of the terrain it travels through.

Ok, so the average of all rivers approaches pi.

Wouldn't it look like two bells with most people having two feet?
Do you stand on every step with both feet?
True, but not /accurate/ maths.
The only pickiness I can manage there is... oh, actually there's quite a lot!
Xen, stop uttering rubbish!
Does everyone stand on the same step with the same side foot?
No, I don't. But I'm thinking that dwarves might.
