I'm enjoying the so-bad-they're-good rhymes (like the many wonderful examples from Tom Lehrer), but what I really want to see are more of the truly bad ones (like Neil Diamond's).

Nothing to offer at the moment ~ can't think of anything BAD enough right now, but I'm still trying. I know there are some truly terrible rhymes out there, some undoubtedly rooted in my memory but temporarily suppressed because they're so excruciating. Therapy might set 'em loose...
