There are many good sources of copper;
I can quote you a score of them here,
But if you want copper that's proper,
Don't buy it from Ea Nasir.
He'll rob you, he'll scam you, he'll bilk you,
And if it's not one it's another;
For all he can get he will milk you,
And then he'll be rude to your mother.

His speech will be sweeter than honey
While he's trying to get you to buy,
But all that he wants is your money,
And you, once he's got it, can die.
He's a villain who's trying to mask it
With a smile and a whimsical joke;
So don't touch his Mystery Basket -
You're buying a pig in a poke.

Don't fall for his charm and his jollity;
Those "pure copper sheets" are quite thin,
And while he's extolling their quality
You'll notice they're more than half tin.
Oh... what? You've already bought metal?
Let's look and see what you've been sold;
You may need a lawyer to settle...
Great Scott, do you think you've bought gold?!
