a rooster serviced all the animal
A farmer wanted to have his hens serviced, so he went to the market looking for a rooster(公鸡,狂妄自大的人). He was hoping he could get a special rooster, one that would service all of his many hens, and when he told this to the market vendor, the vendor replied: "I have just the rooster for you. Randy here is the horniest rooster you will ever see!"
