LOL no way! - I can't believe that Welsh 'sheep shagging' jokes have made it onto this forum.
Being Welsh and living in the USA, i got fed up with the blank looks I used to get, when I was asked "where are you from" and replied "Wales", so I just accepted that not many people here had heard of the country and just say "the UK" now.
Anyway, I grew up with these jokes and still find them funny.
