A farmer comes home with a lively young bull. His two old bullshave fallen on sad days. He's letting them hang around for oldtimes' sake. The minute the new bull is put into the pasture,he starts servicing the cows. At about the fourth cow, one ofthe old bulls starts to paw the ground and snort. The other asks,"Why are you doing that?"The old bull answers, "I don't want him to think I'm one of these cows!"
