Frank Zappa was not known for his serious nature.  He was very good at pointing out the silliness and stupidity of just about anything that could be conceived.  If there was one thing (besides family) that he took seriously, it was music, and he really did not take most of that too seriously, either.  His rock compositions were big jokes as far as he was concerned.  The only reason that it was as complex and involved as it was came from nothing less than the force of his genius.  At the beginning of Yellow Shark, he off-handedly asks to audience to "get serious" (before asking them to put panties on one side of the stage), and one gets the impression that he is at least a little serious.  Lord knows, if Frank is serious about it, maybe we should be, too.
