Poop Fairy

I need to get one of these for my yard - the sign, not the fairy, though I suppose the fairy could work too.  We'd have to negotiate a schedule.

In fact, I could use several of these signs.  Or even better, a couple in billboard size.  I could make a wall of them at the front of my yard.  That might keep the neighbourhood dogs from crapping in my yard, though it may offend the neighbours - just like their dogs crapping in my yard offends me.
