From a Canadian friend:
A pair of Newfies (Newfoundlanders, which I'm informed are none too bright) were sitting in their boat fishing, having an absolute windfall. For hours they were hauling in huge catches.
As the day drew to a close, one said to the other, "This place is unbelievable! We really need to find a way to mark this spot, eh?"
"Yeah."
With that, the second guy rummages around behind him and finds a piece of chalk. To the growing incredularity and exasperation of his friend, he proceeds to mark a large letter X on the bottom of the boat.
"There", he announced with some satisfaction, only to deflate slightly as he met the stare being levelled at him from his friend.
"What?"
"Your'e such a dumbass. Like as if that's going to work, eh?"
Still holding the chalk, the first guy stares back nonplussed.
"Do I have to explain everything? We're taking MY boat out tomorrow!"
