#12: See You Later, Aligator
Do you ever think about how weird it is that there are phrases and rhymes and stories and songs that somehow get past all over the world? I guess it makes more sense now that we are all interconnected, for better or for worse, through the Internet, but think about how crazy it is that these things were transmitted across the world back in, say, the 1950s.
And here’s a great example: how did “See you later, alligator” and “In a while, crocodile” become so widespread that this joke makes sense to most people who read it? Where do we get this shared knowledge about the correct way to bid farewell to large aquatic reptiles? It boggles the mind.
