I really like it when in lyrics and poems different parts of speech are rhymed, e.g. There’s a boy across the river but alas I cannot swim/I never will get to put my arms around him. Also when the (half) rhymes you get are not the ones you expected, e.g. There’s a house across the river but alas I cannot swim/And a garden of such beauty that the flowers seem to grin. And again when cliches are subverted, e.g. wider than snow. There ought to be names for these devices. Perhaps there are.

I don’t think “college” can really be rhymed with “knowledge” ever again. “Porridge” is still fine.
