Keeping Secrets

Three folks can keep a secret shared if two of them are dead.
Otherwise the secret's out, everything that's said.
"Keep it to yourself," I've heard, and "Please don't tell a soul"
which are, of course, the perfect ways to guarantee it's told.

"I've been informed, in confidence, that you-know-who's in town,
but please be very careful, dear; don't let this spread around."
"Spread around!  For goodness sake, I'd never say a word!
You can trust me!  From these lips nothing will be heard."

A lie!  A lie!  A bald face lie!  No secret's safe today!
You might as well hire on a blimp with neon light array.
Take out an ad or post a sign or call up channel three.
Your secret's in the public sphere for all the world to see.

So be aware that when you next reveal a secret thought,
don't waste your breath with "Mum's the word"; instead, I think you ought
to take to heart this proven law, it's truth so aptly said:
Three folks can keep a secret shared if two of them are dead!
