Three bulls heard the rancher was bringing another bull onto the ranch.  


First Bull: "Ive been here five years. Im not giving this new bull any of my 100 cows."  


Second Bull: "Ive been here three years and have earned my right to 50 cows. Im keeping all my cows."  


Third Bull: "Ive 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 Im keeping all 10 of my cows."  


Just then an 18-wheeler pulls up in the pasture carrying the biggest bull theyve 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. Im 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, dont be foolish, let him have some of your cows and live to tell about it."  


Third Bull: "Hell, he can have all my cows. Im just making sure he knows Im a bull."
