If you are interested enough in this title to have clicked on its link, then you probably deserve to read this.
Cow goes moo, sheep goes baaa, but what does the fox say? The fox says whatever they do, just with different signs. What something says is what it communicates, not how it communicates it. If this weren’t true, then mute people would be unable to say anything, which of course isn’t true.
So if you insist on singing the song, which has about five minutes of shelf life left, change the words to “What symbols does the fox use to say?” Just sayin’ (another meme which has already expired).
