Many believe they know the law
Because they were arrested;
Others know how to teach
Because they too were tested.
If you have a religious question,
They attended church;
Mention you've an ache or pain,
They diagnose your hurt.
Should you bring up politics,
Republican or worse,
They'll explain Democracy
Cause they've been free since birth.
Admit your car is pinging,
Your faucets aren't behaving,
The oven isn't cooking right,
Your fridge is warm and shaking,
The air conditioner's out of whack,
Your furnace has turned blue,
They'll tell you what to do:
Change the thermo-coupler.
It's always their one answer.
Say you like this stock or bond,
An investment that's appealing,
They'll  discourse that all agents
Are cunning conniving stealing.
On Monday mention the big game,
They'll re-play, play by play,
As if you slept right through it.
If you hear a rousing band,
Attend a movie or a play,
Know-its are informed critics,
Once they were stagehands.
They pose as friends and family,
Waiting for an opening,
To disrupt with diatribe,
To display how much they know.
I know what I'm on about,
So let me advise you,
I'm a Know-It-All poet,
All I write is true.
So,
Never miss the opportunity
To keep your mouth shut too.
