Amusement park for pigs

Dutch farmers (it is known that they have there smoking - will not specify) Steginku Eric came up with a brilliant idea: why not make a pig small amusement park with one attraction - a mud slide. Bought an old hill hosts the pool and rubbed it in his next to a puddle of mud. Animals delighted with the idea. Farmer is also likely. They say that moving from pigs make excellent skewers.
