Take a whiz on it............if you feel like someone just shot a razorblade up your pecker, you'll know the fence is working.
Very effective. Works every time...

I've probably told this story on here before, but when I was a kid I one of my cousins came up to visit from the city, one of us turned the fence off and we all peed on it and then dared him to do it. He started and about mid stream they turned the fence back on. 20 years later he came out of the closet and our granny was always convinced that peeing on the fence is what made him gay.
