I think that it is not worth offending an ugly rat, because it can always be compared with an even uglier blobfish, which may not share people's views on the ugliness of the rat and will look at it as something magnificent and perfect, just as a blobfish looks at another blobfish :)
I can imagine, on other hand you know there is even then might be some people who will find it nice. So many people so many tastes.
