I'm sorry if I doubt it,
Your plan to tell the truth.
I hear you might try charging.
Perhaps, set up a booth.

If you do I'll surely pay
To witness how it goes.
Truth, when coming from your mouth;
I wonder if it glows.

At that time, I'll surely see
The consequence it brings.
You with angels at your side
And other wondrous things.

Pigs in flight around the town.
Blue moons seen everywhere.
And unicorns and mermaids
Just lounging here and there.

A pot of gold and rainbows
Near Santa's magic sleigh.
Aliens from outer space
Would surely come that day.

I wouldn't miss the marriage
Of Hillary and Starr.
A Twiggy, Oprah Winfrey.
Bill Gates, a movie star.

Yes, I surely doubt it all
Could ever come to pass.
If it did, I'm sure the Gods
Would celebrate en masse.

And I would stand among them
In lipstick and a thong,
Prompting them to join me in
A hot tub sing-a-long.

Wonders would not cease, you see.
In fact, the truth would die.
For when it passes by your lips,
It then becomes a lie.

GREENWOLFE 1962
