Sorry but I must also register a dissenting vote. I love parodies. The more I like the original song, the better I like the parody. (As long as the parody is done well,of course. No art form is enjoyable when done poorly.)Puns are also considered a "low" form of humor, but I love puns too.
All this high/low humor stuff sounds pretty classist and/or racist to me. "That's the stuff that THOSE people find amusing."
