Now there's an idea: smurf lawn ornaments.
But there's something to be said about giving a neighbour: a food item.
Or something neutral.
But JWs have some pretty weird ideas, and will somehow resort to suspecting an item (any gift) is possessed by 'Satan' - this guy>.
You know, I can't think of anything practical or useful that one could do to 'get to them', and I do mean this in a good way.
Eventually, given their track record: they'll be coming to you...if ya know what I mean. <knock, knock>
