Building a wall to keep those damn 'mericuns out

Well, they're going to take a billion or two (or more) out of our pockets to build a useless wall to "keep those damn mezcans out." Aren't you pleased? Hadrian had a wall too. So did Berlin. China had one.

Maybe, once our society collapses upon itself of its own weight, the Mexicans will use this wall to "keep those damn mericuns out."
