This is a set of generators that's meant to be for songwriting, but the "Titular" one is also just fun to fool around with in general, and the "LyriCloud" one would probably be just as helpful for inspiring poetry.
watchout4snakes is a word generator that you can also use for phrases, sentences, or even paragraphs. The phrase generator has different parameters you can choose for "word type" (adjective, noun, etc) and "complexity" (from "very common" to "obscure")... And it's the reason I've written songs called "Werewolf Magnet" and "Abysmal Risotto", so there's that. An example of something from the paragraph generator:
The betting circuitry frees an ancient before the prescription scratch. Beneath a respectable extremist accepts the medical clause. A punch relaxes against the postscript! Why does an addict jam without a special medicine?

Seventh Sanctum is about the closest thing the Internet has to an 'ultimate' generator site. They've got dozens on there, some more impressive (and/or funnier) than others.
From that last one you posted, I got 'The corpse degenerates into a grave candidate.'. Morbid, but surprisingly coherent.

I love random generators! They're great for if you've got art-block, and they're just fun to play with. So I made a thread for sharing generators (including ones that you've made yourself) and the results we get!
Here's a list of generators I use for drawing prompts.
As for sharing results, I'll start! From the Magical Girl team generator, I got: This magical girl team has five members of assorted ages. They have a celestial motif and their uniforms resemble futuristic naval uniforms. Their mission is to defeat a megalomaniacal sorceress and save the galaxy.
