Yeah, verb is kind of a stretch though.

I’ve seen this before and always thought the verb was a stretch since it is definitely not used in modern English, but I do like the idea of forming a sentence this way.

I’m sure there’s a better example in Ukrainian, but

Як як? Ну як як? Як як як…

Not really a pun and not translateable as a joke, but same word that can repeat to form a sentence.

Joke is a guy went to the zoo and friend is asking him how was yak. He replies with yak was like yak.
