"More Welsh jokes please "
ok

An Englishman goes on a walking holiday and stays in a fairly remote village near Snowdonia. He has a pleasant night and in the morning as the sun is out decides to go for a walk around the village.
He says a polite "good morning" to the first villager he sees but gets no response just a puzzled look.
Again he gives a polite "good morning" to another villager...no response.
Rather crestfallen he returns to his B&B, "they're not very friendly round here, are they?" he complains to his landlady.
"i said to several villagers good morning but they blanked me"
"ohhh" she replied, "the word for good morning round here is YAK-YD-AA...say that and they will cheerily respond"
"ok, will try tomorrow morning" he says, somewhat relieved.
The next morning the weather was not so good - thunder, absolutely p**ing with rain and a cold wind, but our visitor decided to go out for a walk round the village anyway to try his new phrase.
The first thing he comes across is a very large articulated lorry, jacked up and with the wheels and diff off - he peers underneath and sees a shadowy figure, and cheerily cries..."YAK-YD-AA!!!"
A man crawls out from under the lorry, soaking wet and absolutely covered in oil...
"F**K OFF, YOU WELSH idiot!!!
