My voice is changing

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!
