the trick of trade

“I am the magician

Now you see

The boomerang in my hand

Once I say the magic words

Do you think it will be there?

“Hah! You don't believe me?

Now look at my hand again

I tell you what I do

I roll up by sleeve here

Now you can see clearly

There is no hidden cost

It is all there in the open

You see my hand holding it?

Now close your eyes

You are feeling drowsy

The boomerang will be gone

1 and 2 and 3 and.....

Are you awake?

The boomerang in your mind

You never see it in my hand

I learn it from David Copperfield”
