Built

There was an Old Man of the Hague,
Whose ideas were excessively vague;
He built a balloon
To examine the moon,
That deluded Old Man of the Hague.
There was an Old Man with a beard,
Who said, 'It is just as I feared!
Two Owls and a Hen,
Four Larks and a Wren,
Have all built their nests in my beard!'
My friend built an aromatherapy vaporiser with a built-in brain scanner
Seems a bit out there, but makes scents when you think about it.
Did you hear about the restaurant they built on the moon?
The food is good but it lacks atmosphere.
I built an electric fence around my property yesterday.
My neighbor is dead against it.
