Mention eugenics, you'll empty the room;
People assume you're the prophet of doom.
This time, before it's a total rout,
wait a second, hear me out.
Here is where, if you listen to me
in a few generations, humans could be.
Sad brown eyes, golden hair,
happy sleeping anywhere.
Great disposition.  Wonderfully nice.
Great white teeth, a breeze to de-lice.
We'd all love nature, swimming like beavers
once we've evolved into Golden Retrievers.
