That's a good one. Here's what happened with 2 Live Crew: Roy Orbison's people got at them for their use of "Oh Pretty Woman", even though they switched up the lyrics to "dick sucking woman" and "bald headed woman", and shit like that. IIRC, the judge ruled it a parody, because they were singing the same melody with different lyrics, kind of like Weird Al. As for the financial outcome, I never got the full story, because we were still on tour at the time, so I'll have to look it up.
