Ezra, while standing in the neighbor's sprinkler: It's the ocean! It's splashing! It's like the ocean! It's a wave!
(btw, Ezra has never been to an ocean, just a sea. But he doesn't seem to believe "the sea" is a real thing.)
He likes to say that things are "like" other things. A cat is like a dog. A scrap of paper on floor is like a leaf, etc. I think it's because I read somewhere that it's important not to correct an early talker too much, so I spent a lot of time saying things like "I see what you mean. It looks like a balloon, but that's Mommy's bra."
