The Hole Song

When you leave,
You leave your hole behind!
When I come,
Its just your hole I find!

When you're hot,
You can be quite conductive.
But when you're cold,
Your not so seductive.

I need you,
to be more,
I need your:
to be impure!

You'll be better
I'm really hoping;
When I add a letter
In a process called Doping!

If you were N;
It would be conductive,
If you were P;
I would fall in your... hole.

This song is actually about the doping of Silicon chips.
