Real people and clarifications

[Paul Mackin]

There once was a person called Real
Problematic though this fact might be
His friends all insisted
He really existed
But we all know better, don't we?

There was an existence called Actual
It was indisputably factual
Yet a thorough analysis 
Brought total paralysis
To this supposed existence called Actual

There once was a list name of Pynchon
That we all think is pretty darn bitchin'
