Essay ideas

I have been trying to come up with ideas or essays, and I have come up with this. Why do people like comidians that are loud and obnoxiouse, and thats their only bit. They only yell and scream and make goofy assed noises but are basicly talking about the same things a normal person would discuss in daily life. I believe that this could become an essay by talking about the reasons go to comidians and discuss why people would like an act like that.
