Three bulls heard the rancher was bringing another bull onto the ranch.First Bull: "I've been here five years. I'm not giving this new bull any of my 100 cows."Second Bull: "I've been here three years and have earned my right to 50 cows. I'm keeping all my cows."Third Bull: "I've only been here a year, and so far, you guys have only let me have 10 cows. I may not be as big as you fellows, but I'm keeping all 10 of my cows."Just then an 18-wheeler pulls up in the pasture carrying the biggest bull they've ever seen. At 4,700 pounds, each step he takes strains the steel ramp.First Bull: "I think I can spare a few cows for our new friend."Second Bull: "I actually have too many cows to take care of. I can spare a few. I'm certainly not looking for an argument."They look over at the third bull and find him pawing the dirt, shaking his horns and snorting.First Bull: "Son, don't be foolish -- let him have some of your cows and live to tell about it."Third Bull: "Hell, he can have all my cows. I'm just making sure he knows I'm a bull."
