There was once a man from the city who was visiting a small farm, and during this visit he saw a farmer feeding pigs in a most extraordinary manner. The farmer would lift a pig up to a nearby apple tree, and the pig would eat the apples off the tree directly. The farmer would move the pig from one apple to another until the pig was satisfied, then he would start again with another pig. The city man watched this activity for some time with great astonishment.
Pigs are the only mammals besides humans which can be sunburned.
A hippopotamus also can get a sunburn. But, than again, a hippopotamus is related to a pig. Pigs cannot sweat. A city boy decided to quit the rat race and bought himself a farm, which included a few sows. He wanted to breed the sows, but had no idea how to go about it.
