Not A Joke
Sheep are not a joke. They are sentient, intelligent, animals. To portray sheep as comic figures is a frequent occurrence, and liable to encourage the misguided perception in humans that sheep do not need to be taken seriously. Particularly, products aimed for children often show sheep as ‘funny creatures’: this could lead to engendering in the children an attitude for life that sheep are not for valuing.
And with an attitude taken hold among the populace, or regarded as acceptable in society, that all sheep are is ‘a laugh’ could be rendered a dire consequence. This would be of sheep being treated badly because of them not being seen as animals worthy or necessary to be cared for well. Could it be that contributing to the highest level of sheep welfare not always being attained is people regarding sheep as a joke?
