Canada has begun construction of a 3000  mile long wall on its southern border with the United States. The  massive project will cost upwards of 250 billion dollars and take twenty  years to build. And the United States is going to pay for it.
                      
 
                      "Look, you guys are sending all your rapists and drug dealers here," said Canada, "so this wall is on your dime."
                       
                      "Rapists and drug dealers?" said an outraged United States,  "How dare you stereotype us so cruelly! You bunch of lily-white hockey  puck-sucking Dudley Do-Rights!" 
                       
                      "We're not just building a wall  to keep out your rapists  and drug dealers," explained Canada, "we're also building a wall to  keep out your bigots, bullies, murderers, tweakers, misogynists, white  nationalists, deadbeats, gun nuts, wing nuts, whack jobs, nut jobs,  mouth breathers, knuckle-draggers and pussy grabbers." The United States  puffed out its chest. "You left out climate-change deniers."
                       
                      The Great Wall of Canada will span from Vancouver to New  Brunswick. It will be two hundred feet tall, and covered in greasy  cheese curds and antlers. Canada will invoice the United States every  month for construction costs.
                       
                      "This is overkill!" exclaimed The United States. "We can't afford this shit!" 
                       
                      Canada scoffed at the United States' claim that it's too  danged broke to pay for the wall. "We can't pay for your Great Wall of  Canada," whined the United States, "the Mexicans never paid us for our  wall to keep out their rapists and drug dealers."  
                       
                      "Boo-hoo," said Canada. "Why don't you just hire some  illegals to help build it? You can underpay them, or better yet, don't  pay them at all!" The United States paused sheepishly before replying,  "We deported them all. We don't have any illegals left."
                       
                      After some creative accounting, The United States finally  devised a plan to pay for the wall. "We gut Medicare, slash Social  Security, stop paving the roads, lay off the police, fire the firemen,  close down the schools, hospitals, airports, national parks, power  plants and the government. We'll have a $250 billion check for you by  Friday."
                       
                      "We only accept cash," said Canada. "And really? You're gutting  Medicare?"  The United States shrugged. "Sure, why not? They've got  cheap dentists in Mexico."
