Buy a railgun! Do it now!
Act before your neighbor does.
Launch projectiles at Mach Five.
Better than the Death Ray was --
oops. should we have mentioned that?
sorry, it's still classified.
But if you can't kill people dead
with a railgun, you've not tried.
No propellant, nor an action,
just a hundred megajoules,
guaranteeing your satisfaction,
not so much your foes' -- the fools.
