Warning Signs

My boss handed me an assignment: design a warning sign for nuclear waste that will make sense to anyone digging it up a million years from now.
My first few efforts focused on skulls, crossbones, frowny faces, festering zombies, and other symbols of slow, painful death.
Then, I realized. If these people of the future don’t understand simple English, that means our country’s been conquered by China. Or overwhelmed by those Mexican immigrants.
Well, screw that. This is my country, dammit.
That’s when I started drawing smiley faces and people with shovels, happily digging, and pouring barrels over their heads.
