Secret Code

Once I had a secret code,

Where A was B, and B was G.

G was K, and K was J;

And J was M, and M was P.

V was X, and X was V,

And U was I, and I was U.

87 stood for Z,

And 2 for T, and T for 2.

O was 12, and Q was 17;

I still don't know what those numbers mean.

That is how we won the war;

My secret code's no secret anymore.

H was 9, and S was 33;

Oh, how that confused the enemy!

Then a recent survey showed

That I don't understand my secret code.
