Frenchman and Brit walking on a beach - they find a bottle, usual thing, open it up and out pops the regulation Genie. OK lads he says, one wish each.
The Frenchman asks that France could be surrounded by a huge wall to keep every one out. OK says the Genie, all sorted.
Asks the Brit what his wish is and the Brit asks if he can ask a question?
Sure, what is it? This French wall, how big is it? Fifty feet thick and one hundred feet high says the Genie, now whats your wish? Fill it up with 'kin water he said !
