Farmers Secret Weapon

Seems that there was a noted gardener who was famous for his wonderful tomato plants. As would happen, one day a young lady asked him his secret for success. He replied that each morning he went out to his tomato plants with nothing on but a robe. He would stand in front of them and flash them. He suggested that she try his method.

A few weeks passed before they again met, and being the gentleman he was, he inquired as to her success. She replied that nothing had happened to her tomato plants, but that he should come and see her cucumbers!
