So.... this is based on what I hoped was the Metanism of the latest WSJ contest. I don't think it was (I haven't solved it yet.... this is one of those days where it's easier to redo a puzzle than to solve it.)
Okay.... Look. "Round Five" means take five things that are not round and make them round. You can make things round by replacing them with round things and you can find those round things in grid (although you'll have to make them round by rounding some letters)
