Klingon Jokes

Canon Jokes

On the audio tape Power Klingon, we can hear three Klingon jokes.

Are Warriors Red?

Q: Doq'a' SuvwI'?
A: ghobe', SuD.

Q: Are the warriors red?
A: No, they are green.

This may be a possible wordplay with the verb SuD, which can also mean gamble, take a risk. But that is more than speculative and definitely not canon. (although conversations with Okrand have verified that he was aware of this wordplay when he created the joke).
Although a perfect match, it seems to be mere coincidence that the colors in the joke correspond exactly to the four modes of thinking according to the HBDI (red, blue, green, yellow) (1) (2). When Okrand was shown this during qepHom 2016 he said that this was really pure coincidence, and that he had never heard of this. Okrand added that it was him who invented that joke, not Barry Levine, the author of the tape.
