Analysis of Nitpicking Paul

I knew a man named Paul
Who thought he knew it all.
He felt it was his job to say
At least a dozen times each day,
"You're doing that wrong!"

He made the workers feel uptight
Each time he said to, "Do it right".
They cheered each time he left the room,
Because he only brought them gloom
And NEVER did belong!

One day they asked if he would leave,
A thought that he could not conceive.
Their message was in written form,
Whose end result was just lukewarm,
Since he found words spelled "rong".
