Last night when I went to bed 
With tangled hair upon my head 
In every way I really was a kid 
It happened without warning 
When I woke up in the morning 
I can't tell you just what happened but it did 

I grew six inches in one day 
It's painful when it goes that way 
And now my skinny body's really achin' 
And my skin just exploded 
With an inch of oil it's loaded 
It's so greasy you could fry a pound of bacon 

My voice is changing 
Out of thin air 
And body parts that once were smooth 
Are growing bits of hair 
My voice is changing 
What does it mean? 
I guess I'll be a real man 
Before I turn 13 

I buy two pairs of jeans a week 
I'm such a tall and awkward geek 
I fall down when I try to play a grounder 
At dinner every night I eat 
A giant heaping plate of meat 
Then go out with my friends for quarter pounders 

And weird emotions come alive 
My hormones are in overdrive 
I've turned into a girl-watching creature 
And all my friends their marks are shot 
But they don't care because they're hot 
For Mrs. Smith the mathematics teacher 

My voice is changing 
I hate to hear it crack 
I pray to God I won't inherit 
Dad's hairy back 
My voice is changing 
When will it end? 
And when will mom stop kissing me 
In front of all my friends? 

Pretty soon I bet I'll 
Be right into heavy metal 
But my parents say at least it isn't rap 
I'll start wearing stupid clothes 
And threaten that I'll pierce my nose 
And tell my parents all they like is crap 

The first girl that I ever kiss 
Will be the one and who could miss 
Our love forever written in the stars? 
But I don't think our love will last 
Unless the four years go by fast 
Till I can use the backseat of the car 

My voice is changing 
Out of thin air 
And body parts that once were smooth 
Are growing bits of hair 
My voice is changing 
What does it mean? 
I guess I'll be a real man 
Before I turn 13 

My voice is changing 
I hate to hear it crack 
I pray to God I won't inherit 
Dad's hairy back 
My voice is changing 
When will it end? 
And when will mom stop kissing me 
In front of all my friends? 

Cha-cha-cha!
