This journal is for way bigger things

(sung)
Now my life's a big blank page
Now Greg Heffley takes the stage
Now I've finally reached the age
Where middle school begins

Elementary school, bye bye
I won't miss you, I won't cry
Buckle up, it's time to fly
Today Greg Heffley wins

In this book, I'll chart my rise
From a kid of wimpy size
To the highest of the highs
Oh, I

[SUSAN]
(spoken)
Come on, everybody! Big day today!

[FRANK]
That's right, summer is over! Let's get you back to school, pronto!
[SUSAN]
And let's get that first day of school picture!

[FRANK]
Greg, will you get over here next to Manny?

[MANNY]
Bubby!

[FRANK]
Where's Rodrick? RODRICK!

[RODRICK]
Let's get this over with

[FRANK]
Are you wearing... eyeliner?

[RODRICK]
No

[GREG]
(sung)
Here's the thing with being me
I'm the middle child of three
Having this much family
Should be against the law
Rodrick is the older son
Likes to torture me for fun

[RODRICK]
You suck!

[GREG]
Manny is the baby one
So Mom and Dad say

[FRANK & SUSAN]
Aww! Baby

[MANNY]
Bubby!

[GREG]
(spoken)
Mom! Please make him stop calling me that

[SUSAN]
Aw, that's what he calls his big brother, and it's so cute!

[GREG]
(sung)
Manny never gets the blame
Rodrick makes my life so lame
Every year is just the same
Cause I
[SUSAN]
(spoken)
Smile, boys! 3, 2, 1!

[GREG]
(sung)
I'm stuck in the middle
Stuck in the middle
Of a mom that Manny, Rodrick Heffley brawl

My big brother tricks me
My kid brother licks me
But in middle school I'll stand up straight and tall
I'll be right there in the middle of it all!

[FRANK]
Alright, kids, hustle, hustle
Pile in the minivan
Greg, would you sit up straight?

[RODRICK]
Can you say loser, Greg? I can

[SUSAN]
Rodrick, don't tease your brother
Greg, please mop up Manny's drool
And don't forget your diary!

[GREG]
Journal!

[FRANK & SUSAN]
Here we go, it's middle school!

[ENSEMBLE]
Ahh, middle school
It's middle school

[GREG]
I may not know what's in store
But everything I was before
Changes when I reach that door
Oh, I
I'm stuck in the middle
Stuck in the middle
But in middle school, I'll stand up straight and tall

A new world beginning
The top of the inning
And I'm right here in the middle of it all
Yeah, I'm right here in the middle (In the middle, in the middle)
