The makers of this fun vid took the expression "draw your weapons" and turned it into the premise for a short in which combatants must sketch their own arms out of chalk.
I really like the fact that they went out of their way to make the chalk weapons look super flat, and the 'splosions are a nice touch. Sidewalk chalk art has never seemed so dangerous!
