What I found strange is he was attacking other comedians and their style of comedy when his one trick is the sick joke. From an artistic point of view he isn't exactly Stuart Lee or Eddie Izzard. He is funny because he shocks with sick jokes.
I don't get offended by his crap jokes, he's made a living out of just being an offensive nob, probably would have gone down a storm in the 80's, but personally I prefer some clever humour - Bill Bailey - Sean Lock I like, personal preference ain't it.
I dont find Frankie Boyle offensive, funny or talented.
Frank Skinner did the look in the back of a spoon gag about 10 years ago when talking about Barry Manilow, it was a miniscule comment as part of a much bigger joke, and it wasnt directed to be offensive in anyway. Frankie Boyle stole the joke, used it solitarily and aimed it at Rebecca Adlington with the sole purpose of offending her and getting the shock reaction laugh and as a publicity stunt. Just like he did when talking about Katie Price and Dwight Yorkes son. Some people migth find that funny, but it's hardly clever, witty, well-written comedy is it?
I tried to watch his stand up but found it so boring - he seemed to go on endlessly about Susan Boyle? His autobiography is quite interesting though - like so many 'comedians' he is evidently suffering with depression and other mental instabilities, hence his struggles with alcohol. I think he's had his 15 minutes of fame.
