Ode to the Margin

Oh margin
Its how I know what I'm charging
When I make my decision
It's the the margin I envision
Oh margin

Oh margin
Credit where credits due
That because of you
Ill know who to give the job to
When A makes 3 widgets
and B only makes 2
Oh margin

Oh margin
When a friend wants one more
Because hes sure that he'll score
Ill remind him hes had a dozen
And that she might be his cousin
He'll insist to stay
And Ill call it a day
But when he calls in the morning
Ill know what to say
You didn't need that last drink
Don't you know how to think?
How good was the last?
Don't you remember the past?
When five was alive
And six was in the mix
Seven was heaven
And eight was great
Nine was fine
And ten is when to end
Marginal cost equals lost
But listen you did not
And eleven was a shot

Now at a dozen
Doing a fair share of buzzin
You stand outside the door
Of said maybe cousin

There in your hand
Is unlucky thirteen
And you drank it down quick
Because you weren't so keen

So here's my advice
I wont say it twice
The beers not such a bargain
When its your cousins room that you barge in
You got to think at the margin
Oh margin
