What was interesting to me

I thought the fact that wagner wanted a clown to be his servant.  I mean a clown is as worthless as a rock in a pond.  I would rather have an animal as a servant because they would actually do something like entertain me.  I just thought it was weird that he would ask a clown because clowns are know people that don't really do anything but make people laugh.  I thought it would be better to have a peasant do it or something.
