"Ode To Lactose Intolerance" by Alexander The Poet 

Eight glasses a day,
Of milk, they recommend
But I need to say,
For some, milk's not a friend

Because what you get,
After drinking, much milk
Is shit that is wet,
And shit that tries to bilk

You are, what is called,
Lactose Intolerant
Shit needs to be hauled,
Stay in your ass, it can't!

But there is good news,
Diarrhea will pass
And then you'll refuse,
More milk, filled in that glass!

THE END
