There is an IWW song in which "wages" is rhymed (appositely) with "outrageous".

IMO the worst rhyme in a song -- possibly in all of English prosody -- is

There is a tree in paradise,
And the pilgrims call it the tree of life.

The last vowel is spread over 8 beats, during which the naive listener can wonder whether the word is going to be "lies" or, perhaps, "lice". Nevertheless, I like the song.
