this is interesting topic.. i dont thnik the barrier is the language, its just more cultural...
i know i dont have to generalzie, specially coz what i will say wont concern most of the US dudes on this board but, americans still thnik in very puritan way, they still are schocked with some topics. just look at the mess madonna and britney did hahahaha lol this is is a very good example.
i dunno how it is in england but here in france we use lots and lots of "schocking" in a different sense. most of americans i know dont understand jokes when they are not obvious. english perfectly understand and i thnik they make this kindof jokes really more than french. another good example :if you joke about aminority (blacks jews etc) youre taken as racist in the US, i just thnik this is just a "political correct" mind people have over there.
no hard feelings involved, dustin your e anic edude !=)
