It's a cut.

ME: "See the cut on my arm?"

WIFEY: "That's not a cut."

ME: "What do you mean it's not a cut? It's a cut. A big cut."

WIFEY: "It's not a cut."

ME: "Cut."

WIFEY: "It's a scratch."

ME: "A scratch?? It ain't a scratch...it's a cut!"

WIFEY: "Scratch."

ME: "It's a cut! Look at it."

WIFEY: "How did you get your scratch?"

ME: "I walked into a rack at the store and scraped it."

WIFEY: "Scratched it."

ME: "It's a cut."
