Songcabinet has some interesting ideas (yea, I'm not on vacation, but I still read it). I would venture to agree on his theory on Tom's note from Taxi: It probably wasn't really the "obvious rhyme" but more the originality/power of the particular lines.

Great lines
can have perfect rhymes
Near rhymes
serve their purpose, too

Story told
images unfold
Great lines
You and I persue
