bad comedians

I went to the lecture yesterday it was about bad comedians. i learnt that there was two types of comedy people laughed at which was subversive and reactional. Now what i learnt that reactional comedians joke about certain taboos such as racist jokes and jokes against women thery joke against the sat us quo the same is to say with subversive comedians but they mainly take the piss with there jokes i think a example of this is Ronnie barker who players fletcher in porridge he maybe taking the piss when in the first episode by taking the piss out of two religions such as Muslims but he says muslins also out of Jew's because godber who says hes church of England then he says he would have a better life if he was a jew in prision but the joke is the doctor who supposed to examine him will now he isn't a Jew since he hasn't been circumcised but the joke is he says crimucstansed so he provokes a reaction but also is subsrvive because he is taking on the system in which his case is prison. how can you been comedy my simple answer is you cant because comedy is meant to make you laugh so its entertainment it the wont make you go aginst the system becuse you fell happy when you fell happy you will let everything pass you by but if you do decide to ban it it will just go onto the underground and just will become more popular.
