stan up comedians are the best.
some recent 1's ive seen.
Jim Jeffries - really dont watch this if ur easily offended infact dont watch it if your difficult to offend.
Frankie Boyle - Excellent very typical scottish / british humour
Russel Howard - very good something a little less offensive
Lee Evans - new DVD yet to watch !!
some older 1's that need a mention.
Jim Davidson - very very crude!
Mike Reid - again crude but excellent.
i think the majority of the above is very much british humour not sure if its the type of thing americans find funny?
