The green one

Scene: Election day. Julia is standing the required 150 feet away from her polling place with a sign reading "Yes on 4! Save the economy and the planet."

Security guard: Hey, what's question four?

Julia: It's asking the legislature to take subsidies away from industries that pollute a lot and give the subsidies to building green jobs instead.

Guard: That sounds good. All that green stuff. You know, I bought a truck the other week, and the guy at the lot says you can have it in two colors, the blue one or the green one. (With a wise smile.) And I says to him, I'll take the green one. It seems like things are going in that direction, you know?

Uh, sir? It doesn't actually work like that.
