I haven't closely read the whole, long thread, but a scan reveals it to be a mishmash of genuinely objectionable rhymes (e.g., "kelp/help" - an OK rhyme as such, but my laws, nobody should be allowed to write "the beach is deserted except for some kelp"

; "can you cook and sew/make flowers grow" etc.) and then some that are really rather charming.
It beats me how anyone can slag the last verse of "Spirit on the Water," for instance. Or, "a gal named Honey/took my money/she was passin' by" - sure, the money/honey rhyme is hackneyed, but the net effect of the verse is a marvelously compact depiction of the classic dilemma: boy meets girl, boy spends money on girl, girl buggers off.

That's neatly done, especially when matched with Bob's inimitiable delivery.
Then there's a bundle of
outrageous rhymes. E.g., "outrageous/contagious," "January/Buenos Aires," "sons of bitches/orphanages," "subpoena/Angelina," etc., etc.. One part of Bob's toolkit is this willingness to bolt together two words that nobody else would dare to. There's a sly humour to such rhymes, and calling them "bad" strikes me as a bit ungenerous. "Fun" might be closer to the mark.
Conversely, the sort of thing that bugs me is
ponderous rhymes. For instance, "breath" and "death" are a hard combo to get away with ("sleep is like a temporary death" being a rare weak link in that otherwise wonderful song). "I dreamt of my future wife" is a
great line, but its partner - "this version of death called life" - is one wince-inducing renegade that almost kiboshes the whole tune. "Strife/life" is another pair of evil fraternal twins, inflicting harm on "When the Deal Goes Down" and "Red River Shore;" whether the context is adequate to save these songs from the resulting carnage is for each listener to judge.
But basically, I'm surprised by some of the candidates offered in this thread, as their nomination seems to show a distaste for some of Bob's most characteristic moments as an artist.
Excellent post. The whole point of a song like Angelina is the outrageous rhyming - that's what the song is about and as such it is brilliant.
The ones I hate are the ones where Dylan seems to be taking terrible rhyming seriously, e.g. "No Time To Think". He has nothing whatever to say, but is using meaningless rhymes in place of thought.
However I think the winner (or loser) in the end has to be the couplet Alouette quotes from Joey. This is so bad I feel my eyeballs shrivelling as I read:
This is pure McGonagall.
