Such confusion at work yesterday! They had plastic forks that look like metal! (It is hard to see with this picture that I took with the crappy iSight in my computer. As my real camera was stolen, we must rely on the cameras built into other devices.*)
But in real life this plastic fork really does look like metal. Total trompe l'oeil win.
*I tried very hard to make a joke about using this as an excuse to never run for congress, but none of them were funny. The real reason that I would never run for congress is that my political ideas are even crazier than those of my elected representatives.
