An Unlikely Sentence

Just a short observation today. I learned the word 'insalubrious' from a vocabulary-building game. It means, according to dictionary.com, unfavourable or detrimental to health. I'd never come across the word before so I checked the definition and asked the game to use the word in a sentence. This is the sentence the game generated: 'That looks like an insalubrious dog.'

I would just like to know when that sentence has ever been used in the history of the world. Who talks like that? Although, by the same token, who spends their day playing vocabulary-building games?
