What is the English translation of the "The Funniest Joke in the World" from the Monty Python Flying Circus comedy sketch in 1969?

"My dog has no nose."
"How does he smell?"
"Terrible."

This is commonly given as the translation. The actual words in the episode are nonsense, and have no actual meaning in German.

You can see the "German" text of the joke at this link. As noted there, it is not actually in German (some words are only German-sounding), and has no meaningful English translation. In "German", it reads "Wenn ist das Nunstück git und Slotermeyer? Ja! Beiherhund das Oder die Flipperwaldt gersput!"

At your own risk, you can watch the sketch for yourself at https://www.youtube.com/watch?v=q9XJeL2MNpw.

In it, they say Hitler "just could not match" the humour, demonstrated by him telling the dog's nose joke (in English subtitles). The "German" words to the funniest joke, used to lethal effect by the British are, as described above, nonsensical gibberish.

The Wikipedia entry for this joke also confirms that it is nonsense.

In the sketch, the Nazi attempt at their own V-joke weapon was the old chestnut: "There were zwie peanuts walking down the strasse, and one was assaulted (a salted) peanut."

If you try to input the "German" into Google Translate to get a version of it, it yields only links to this joke.

Google translate now yields: "FATAL ERROR"

Methinks someone at Google has a Pythonesque sense of humour.
