Oh what to do, what can I say?
It's wonderous how day by day
You further add to our dismay
And tilt the truth your own sad way

Your pressers are a work of art
A bigly wheeze of air and fart
You somehow seem to think you're smart
But I'd rather have Homer, or Bart

You've even got my pen tongue tied
Blood boiling and brain half-fried
A 'personality' misapplied 
Rarely Jekyll / Mostly Hyde

Some thought you were up to the job
You're great at stirring up the mob
With tiny brain and a big gob
But would you were not such a knob

You really don't have any clue
I pity those who work with you
For loyalty's not what you do
Your only aim's to win and screw

I've not said who this is about
But reading this might make him pout
And make him throw his dummy out
Then carry on without a doubt

Not sure about this one - but for now I think it's out than in?!
Prompt was "Boy you've even got my pen tongue tied!"
