I thought this one was not bad:

    [write a joke about thinking machines and the idea of tropes]

    it's funny how enemies to lovers is a common trope that's uncommon in real life and lovers to enemies is an uncommon trope that's common in real life

I think the word "funny" in that line, is being used in a common way to mean "ironic". Which is both good use of language, insightful and accurate, but not actually funny.
