His art has nothing to do with controversy or trying to make money. The idea is that Jesus was crazy and might have been a "good person" but he wasn't the son of god since god does not exist. Much like the Lenny Bruce comment noted regarding electric chairs. We associate criminals and lunatics with electric chairs today and they probably associated crucifying the same. We wouldn't wear an electric chair around our necks so why a cross.
By the way it isnt boring, it captivated you enough to write a comment on how boring it may be. Art is supposed to invoke a response whether positive or negative.

I think that he has done his job.
