Bush Golf

Jay and Rob were playing golf at a foggy par three near Corner Rapids, and could see the shrubs, but not the island. Each hit their ball anyway. When they paddled to the green, they discovered one about three feet from the cup, while the other somehow had gone directly in. They tried to figure out which ball belonged to who, since they were both using Titleist number threes. Unable to decide, they returned to camp and asked Rod for a ruling. After hearing their story and congratulating them both on their superb shots under such adverse conditions Rod asked, "OK, so who was playing the yellow ball?"
