What goes out comes back again,
like a boomerang and Rin Tin Tin.
Boomerang, a rangy tang tang,
The Old Man of the Forest,
Words that have left,
But the world is our oyster,
When we plunder for profit,
Pendulums swing to and fro,
In a world of hurt a song was sung,
What goes around, comes around,
Boomerang, oh boomerang,
For the universe is the limit,

I started a silly poem about boomerang wordplay and it got serious.
