Damn Dwarves

What I like of this one is that it's a fountain of several interpretations (at least for me):

Old man wears glasses (so he doesn't see so well) and is passing the lawnmower by the garden without realize a missil has just fell from sky. Thinking it should be another of his wife's dwarves he's going to make it go off.

Old man & grandma live in a country which is in war, but it had become so common that they continue to live their lives unchanged; so, every bomb that appears in their garden they paint the explossive head as a little decorative dwarf and put it semi-buried in their front yard.

Grandma is scared as she sees dwarves emerging from the green, as they are the explossive heards of missiles that the people who live in the shallow inside of the earth fires and it falls to 'their ground', meanwhile, in this side of the soil, another war is happenning, so a missil falls to the ground (our ground) too. What would happan if two missiles coming from opposite worlds collide?

Please give your ideas !
