Exactly, life's too short, have some perfectly harmless fun that provokes the local moonhowlers. You have to do these things or life becomes boring.
The other option is when you have a neighbour from hell, drop a bean or two at the back end of their garden where there's likely to be bigger bushes/plants/trees and it will be of a certain size before they notice it. Then sit back in a chair with a few coldies and watch the argument between husband and wife unfold.
You get a certain satisfaction from that, or so I'm told anyway...
