Catharsis isn't art. You can't rely on catharsis to get a laugh. Because guess what? People do laugh when something's shocking, but that is, to me, the absolute fakest of laughs. That's not something that sustains a television series, or a movie, or even 45 minutes of a stand-up set at Carolines.
“Only in art will the lion lie down with the lamb, and the rose grow without thorn.”
