 Had a donkey on their farm where he grew up in Texas was part of the time. And when he was three or four, he came in, he walked into the house and announced that the buck, the donkey that was named Buck, that he wanted to be called Buck, too. So that was fine with the family, and the boy's name became Buck from then on. Yes, Buck came from a donkey's name, Buck, on the farm. So how about that?
