I remember when George Carlin opened up the swearing thing with his '7 words you can't say on Television'. I found that so funny. But it was like the gauntlet fell or something. A few decades later and much of club and late night comedy finds it's self depending on swearing to be funny. I think it is a part of the generation that is coming up now because even comedians, not known for that in their acts, seem to adjust their material to accommodate the younger audience. I read the review of stand up Tim Allen's show and the critic wrote exactly that. Saying Tim's show had decayed into a constant punctuation of 'F'ing that seemed to be his attempt to suit what was a younger audience.
I have noticed this about my local stand up clubs that are open mic, amateur friendly venues. I listen to the amount of swearing in a piece and think to myself...How would this act be able to go to the next level?Being Cruise ships, or TV audiences, when the material is so filled with swearing that would not be allowed in those venues. Some say the hard sound of K's and T's are needed to bring emphasis to the phrase. So that something funny could be made funnier using that. I agree to a point. But when your use of those words finds it self in almost every sentence spoken, it becomes apparent your depending on it to carry the act to 'funny'. And worse, the audience isn't stupid and they recognize this. So that your material isn't original anymore it carries the same brand name as always "I'm only 'F'ing funny"
