I think his patter is marvellous. I saw his show live once & my ribs hurt from laughing so much.
His travel shows are really good too & he is a "people-person" without any pretentions & says what he thinks, which is great in my book.
Interestingly, he does not really tell jokes like most comedians do, he just tells stories from his perspective & touches on subjects that are embarassingly funny.
It does amuse me when people say that he is crude & irreverant. Unless anyone has been living under a stone or on another planet then they should know his brand of humour & just should not watch his shows.
In common with other comedians he will tell the same story more than once but the greatest part of each new show is brand new material. I am impressed that he always does some local research of the area he is performing in & includes some of it in his show.
So, for me, probably the funniest guy alive today.
