Whoa ... This Is Far Out !

Modda used to say something about ducks like "if it walks like a duck then it quacks like a duck", i don't remember it correctly, but it was quite interesting!

Googled it:
The phrase "walk like a duck" is part of the common idiom "If it walks like a duck and quacks like a duck, it is a duck" (also known as the Duck Test). It means that if something acts, looks, or sounds like a specific thing, it is most likely that exact thing, no matter how people try to label or disguise it

Really Interesting!

I have a minor twist on it though, like for example one time during a discussion about graphic novels, whether or not they're comic books, and somebody was insisting that they're not, I said "Well you know what they say: if it walks like a duck, and it quacks like a duck, THEN it ain't a comic book"

Or my quickie version that I also use, "Walks/quacks/duck"

Not everything in the universe is a duck 🤔
