Conspiracy!

Grassy knoll and inside job,
Right wing crazies and the Mob,
Live for free inside his head
His name's "Paranoia Bob."

Elvis isn't really dead;
Literatti at the Fed,
What's an average man to do?
Wear some tinfoil on his head!

Here's the thing (which isn't new)
Sometimes paranoia's true!
But it must not wreck your day
Nor your life, which you would rue.
