Recipe, How 2 make a teenager

I just found out a new recipe,
Try it adults if you dare.
Here is how to make a teenager,
But please people beware.

Add to a bowl,
A clump of growing pains.
Then carefully add,
Some extremely harsh stains.

Pour in some acne,
Mixed in with some coke.
For a boy add some
Yolk for a bit of a joke.

For a girl add some sugar,
So she'll be nice and sweet.
Add some exam answers,
If you want a bad cheat.

Put in a wig,
If you want nice long hair.
Add in some candyfloss,
If you like the fair.

Stir in some CDs,
For a good musician.
Put in a rabbit,
For a bad magician.

Chuck in some cheese,
For some scary nightmares.
Or pour in some bats blood,
If you adults dare.

Put in a mirror,
For a teenagers who is vain.
Then finally think of,
A good decent name.

Stir it all up,
So it's nice and thick.
Pour it all out and
Runaway quick.

When you return,
You'll find someone standing there.
I hope you get on well,
They'll be needing good care!!
