The yardstick I use for any poem, whether it rhymes or not, is its originality and/or cleverness or insight. I have seen too many well-structured verse and meter pieces that are altogether forgettable. I mean you've forgotten the first bit before you have gotten to the last bit. Okay I am being a bit harsh I suppose. But I think if you are going to rhyme in this day in age, you got to bring something new and different to the table.

Was it futuristic octopi?
Or ladelled soup into a basin?
I came, I saw, I conquered,
Turned my brain into a raisin

Your poem is so much fun and the words leading up to the rhyme are every bit as interesting as the punch words. Well done.
