Step 2: Wait for two weeks
Step 3: Take the canvases off the highway, and take off the duct tape (if any sticky stuff comes off, just leave it)
Step 4: Bring one of the canvases over to a modern art museum, and sell it for 1,000,000+$
Step 5: Sell two more to famous modern art museums
Step 6: Auction off the remaining seven for islands in the pacific
Step 7: Build a fake nuke-silo
Step 8: Launch a "Nuclear" strike on North Korea
Step 9: They will retaliate, the United States will retaliate against them, North Korea will attack the United States, European powers will begin nuking North Korea as well. Someone will accidentally miss North Korea, and hit Egypt. Egypt will create lots of nuclear weapons, and attack Europe and the USA, but due to inexperienced craftsmanship, they will hit half of the middle east, and parts of South America. All the world will begin nuking itself, while you move to Antarctica during this time
Step 10: Radiation all over the earth will deplete the ozone layer, and Antarctica will heat up to tolerable levels, while the equator fries. (haha, instead of french fries, France fries, although its not that close to the equator... shut up)
Step 11: Live off of penguins and walruses (walri?) for the rest of your days
