Ranga, my good friend, was well-known on the usenet for his rapid-fire rhymes. Ranga had a slight variation on good old edit-build-run-core-dump loop. He went edit-build-while-building-post-scathing-rhymes-run-while-running-post-scathing-rhymes-core-dump :)
Check out some of his stuff.
Samir Dhume posted some fun rhymes too. This is only one I have around.
