Top of the world to you

So, we all know where North is.
And where South is.
East, you can always keep going East.
Same with West.
But where is the top of the world?
Because there is no actual top and bottom of the world.
Or is that true?
It isn’t, okay?
Anywhere you sit when you’re feeling great, really.
Everyone who sits while feeling great is sitting on top of the world.
Except for Don.
He’s not a happy guy.
He’s always sitting on the bottom of the world.
We don’t like Don very much.
So, we tell him to stand up and leave.
