I asked ChatGPT (3.5 turbo) for some examples of 双关语 = "puns". Among its examples is:
Why are musicians always late? Because they're always tuning. [my translation]
I asked ChatGPT to explain the joke, and it said:
I understand 调音 literally means "to tune" (a musical instrument), but I don't get how 调音 relates to 调整时间 = "adjusting time". It should be a pun of some kind, so maybe there's a Chinese word which sounds like 调音 and has a relevant meaning.
It's also possible this pun makes no sense at all.
Question: How do I understand ChatGPT's joke?
