I haven't heard this song in years, I plowed through most of the discussion pages about the song and sorted out what I feel is a comprehensive list of all the verses. I tweaked some words here and there to suit the rhyme, meter, cadence, and memories I have of the song. Some of the obscure verses needed a complete rewrite, but the theme is still unchanged. There was one I just couldn't figure the meaning of, and consequently omitted. I can't wait to use this at camp next week.
I hope you all approve.

There was a strange old butcher, whose name was Dunderbeck
His specialty was sausage meat, and saurkraut, and speck.
Then Dunderbeck invented an incredible machine,
That ground things into sausage meat, The Dunderbeck Machine.

Oh Dunderbeck, oh Dunderbeck, how could you be so mean?
To ever have invented the sausage meat machine?
All the dogs and rats and pussy cats, will never more be seen
for They'll all be ground to sausage in the Dunderbeck machine.

He had the finest butcher shop, the finest ever seen!
And that's where he invented, that terrible machine.
But some began to think, that maybe something wasn't right,
When dogs and rats and pussy cats went missing in the night.

So if you own a dog or cat, you keep them under lock
Cause if you don't, I'm telling you, you're in for quite a shock!
For if you buy them sausages from Dunderbeck, right now
You'll hear those little sausages go squeak and bark and meow!

One fine day a little boy came walking in the store.
He ordered up some sausages and eggs a half a score.
The boy began to whistle, and they whistled up a tune,
And all the little sausages, they danced around the room.

One day the meat inspector came a knocking at the door,
He said, "I've heard of your machine! Your bribe is gonna soar!".
Well Dunderbeck got angry and he pushed him in the meat.
Then he fired up the old machine and now there's more to eat.

One day there was a shortage, and there was no meat to grind.
So Dunderbeck he called the pound to see what he could find.
They said, "We're out of business, we can keep the strays no more."
"But we'll refer all our future finds directly to your store."

Have you ever wondered, when you go to summer camp.
Why the food is good and plentiful and never gives a cramp?
Cause early in the morning you can see the trucker go,
And the sign upon the driver door is "Dunderbeck Meat Co.."

Now, Dunderbeck, he had a wife, the sweetest ever seen,
He left her home alone to weep while working his machine
She grew morose and leaned too close, undressed her by the seams
And no one ever saw the dress come out from the machine.

One night when he was working the machine it would not go.
So Dunderbeck, he climbed inside to see what made it so.
His wife she had a night-mare and came walking in her sleep;
And she gave the crank a hell of a yank and Dunderback was meat.

She woke up when she heard her love depart through the machine,
But seeing opportunity, she threw in herbs and greens,
She had a sale and many tales of the finest sausage seen
Now there's a little bit of Dunderbeck in all the meat machined.
