“You take a cigarette out of the box. You don’t have a lighter, flint stones, matches, candle, anyone else near you and no lit cigarettes either. How do you light it?”
If a “serious” puzzle:
1) you have some phosphorous handy.
2) crack an incandescent bulbs glass, and use the filament.
otherwise:
1) shake a few tobacco leaves from the cigarette. you’ve now made a cigarette lighter!
