A fun game to play on Google Maps Street View is to go to Johannesburg or Cape Town and time how long it takes to find a home that doesn't have a spiked/barbed-wire/etc. fence or wall.
In my slightly upmarket Johannesburg suburb I would guess about 80% of the houses have electric fences. You can figure out how old the installation is by the number of strands the fence has. It varies with fashion.
The other fun game is swapping stories about the dumbest way you have shocked yourself on your own fence. Mine was by trying to lift a branch of my fence while barefoot using an aluminum pool pole. I thought my wife had turned the fence off.
