Question

What country where you own land is it all the way to the center of the earth. Which means no tunnels or anything can be built under your land?

Answer 1

I'm going to make a lot of money out of this.

In my back garden I have dug a hole 15 miles deep.
Every day I climb down the ladder (have you got any idea how many rungs there are on a 15 miles ladder? A flippin' lot, that's how many - ) and stand at the bottom of my hole.

Then, everytime someone comes burrowing their way through - I charged them a toll fee.

Good idea, eh?

No one has come through yet - but they will, and I'll be rich. Rich I tell you.

In the meantime - anybody want a big pile of earth?
