The young farmer was getting horny at the sight of the farmgirl whom he was interviewing for a job. He thinks if he could get her horny as well, he might strike lucky. As luck would have it, his cow was just being serviced by his neighbour's bull and he took her around to show it to her. He said, "I'll like to do what that bull is doing". She replies "Why don't you? It's your cow".
