'm sitting on the student center steps eating my lunch and throwing bread at pigeons. Next to me in the courtyard is a display of alternative-fuel cars featuring a pickup truck that says "Fueled by Natural Gas" on the side.

This construction worker walks up to me and sits down next to me with his lunch box. He starts talking to me like he knows me, and he sounds annoyed.

"What the hell would I want that for? A truck powered by natural gas? That costs more than regular fuel!"

Somehow I think he might be running on a lean mixture, himself.
