I like a lot of parodies. Its possible to parody specific songs, like Barnie, or parody a form of song, like insipid children's music, or use a popular song with altered words to make fun of another topic of the day. Its very difficult to effectively parody excellent stuff. Parodies work by highlighting and and expanding on the absurdities or weaknesses in a song or form. Good parodies can last longer than the original until they in turn become hackneyed and re-parodied. Its a fun process, like bursting ballons.
