A Canadian and an American were hunting in Canadian woods when a Mexican runs across the field and the Canadian shoots him in the back and kills him. "You can't do that!" cried the American.
"No, no, it's legal here in Canada " replies the Canadian.
Later that night the American goes and buys some beer and puts it on the roof of his truck to open the door. Just then a Mexican runs by, grabs the beer, and runs away. The American thinks "No problem" and he shoots him in the back and kills him. As he is getting his beer the police come and arrest him.
"But I thought it was legal to shoot Mexicans here in Canada!" protests the American.
"Well yeah," says the cop, "but you can't use bait."
