They all help each other and it goes down exactly like how Kevin hart described it. They take notes during each other's stand ups and give each other advice and critique after. I forget where but Chris rock did an interview where he, another comedian who I'm forgetting and chapelle were performing. This was recent, during chapellle current comeback tour or w/e. After chapellle performed Chris said him and the other comedian looked at each other and threw thier notes away because what they jotted down paled in comparison to what they had been noting.
