How to steal a heart

(I should start with saying that this book is the product of inside jokes with my friend and I. But anyways, 20 points if anyone could get what the discription is a parady of.)

Two classrooms alike in humor,
In fair barrhead where we lay our scene,
From old rules break new secrets,
Where these secrets make honest students liers.
From the comedic timing of these two bros,
A pair of Star-crossed teachers plan their lives.
Whos misadventures lead to change.
Do their struggles change the rules of old.
The faithful passage of their untold secret,
And the persistence of a higher power,
Even with help their secret could not be kept,
Is now the typed words upon your screen,
The which if you read with close attention,
What here shall miss, our toil shall strith to mend.
