Fun fact: If you’ve said “Fuck you whale”, you don’t need to say “fuck you dolphin” as all dolphins are whales anyway. It would be like saying “Fuck you, Great apes (Hominidae) and fuck you human”
But you can say it if you want, it’s just superfluous, but many of life’s pleasures are.
I guess one upside of living in a country that uses both metric and imperial frequently is that these things tend to click pretty quickly. The lack of consistency is annoying, though.
