I think the most prime LLM content I have seen was "cook your chicken to 104 F, then consult Goku to sense the power of the chicken to see if its been cooked enough".

I've mostly done text generators using template filling (where a template can be another template), with no actual intent of parsing text. I've also written text parsers, but that was for the purpose of grammatical annotation (actually did one as the first group programming project at uni).
