Escher sentence

An Escher sentence is like a puzzle for words. It's a sentence that starts at the beginning, goes on and on, and then comes back to the beginning again, like a circle. It's called an Escher sentence because it's like a drawing by an artist named M.C. Escher, who made pictures that seem impossible, but are really very clever. Just like an Escher sentence seems impossible, but it's really just a really good trick with words. Think of it like a loop in a rollercoaster, you go up the hill, slide down, and then end up where you started. That's what an Escher sentence does, but with words instead of a rollercoaster.
