Note: This one probably works best if you have the music with it.
It's based on a Dutch song ("Kabouter Pim", written by Harrie Geelen and Joop Stokkermans),
so I doubt any of you will be acquainted with it :-)
I made a slideshow (with subtitles!) for youtube to go with this.
The permanent code to find it should be ce3DXR4XGWE (copy into youtube's searchbox),
but it's possible that for starters you need this address:

http: youtu. be / ce3DXR4XGWE
(translate to internet speak)

If it remains a problem, let me know and I can send you the direct link in a PM.

The Major and the Code

.

Hey, do you know the story
Of the major and the code
Who totally by accident
Heard of the Mairzy Doats
The message wasn't meant for him
He heard it by mistake
But if it'd bring him Nimrod
He had a code to break!

The letter V becomes P
When preceded by E, F, G or T
And not followed by C
But only when the final letter
Of the last word is D
In the Royal British code!

That clearly was the wrong one
For the message was a mess
The General – a sceptic –
Observed the major's zest
Another code, another try
Write down and cross it out
Until, at last, triumphantly
The zealous major crowed

F stands for C or for T
For you see, it's depending on the D
Whether U is inverted by an umlaut
To a Q or P or G
That's according to Pfeffenberger's code!

That may be the solution
For the Pfeffenberger code
But it made perfect nonsense of
The line 'bout Mairzy Doats
However, our major's
A real persistent man
He took another paper
And he said, "I'll try again!"

The letter A is transformed to a K
When preceded by a J
And the word has no F, R, X or M
Except when S becomes an O
In the rules of the old inversion code!

"Sir! Get me some more paper!" he called
"No code can get me down!"
The General regarded
Our major with a frown
"How many ciphers will you try?" he asked
"We could be up all night!"
The frenzied major just exclaimed,
"This time I'll get it right!"

The letter B here replaces the E
When it's followed by a G
Looping back through the T, U, V, X, Z
But that's exclusively with P
In the new loopy doublesided code!

But suddenly a prisoner
With bin and broom came in
The table was a paper pile
And he picked one up and grinned
"My, my, if that ain't Wellington!
The code old spies go by!"
The General, he smiled and said,
"Why don't you have a try?"

Okay!

"Now let me see what it says...
Secret plans hidden Hilda's desk
Was that what you had?"
"Yes! Oh, yes!" the major and the General said
And off they went
Chasing wild geese
For that was the intent!
