From Val Sigstedt
The first time I heard about the fly-in-the-urinal means of manipulating behaviour (22 June, p 32) was a story about a bar with a cure for unruly drunks. The bartender would wait until a particularly bad boy went to the toilet. There was a bare wire strung across the back of the urinal, and the bartender had a way to let a live cockroach run out on it. Of course it instantly became an irresistible moving target, but the wire was charged, and the miscreant got instant enlightenment.
