Parody and fair use

Depending on the topic and the way you use the "art" will depend on if it is a libel suit or not. In the case of SNL, i think it is fair use. Every one and everything they parody is in the public eye. It is very case by case subjective, and i think it should be up to the artist. It is the argument between keeping the original art safe and not keeping other people from being creative.
