On a restaurant menu, the largest serving of steak available.
"Yes Ma'am. I'll have the cowboy killer with a potatoe on the side."


Customer: "What's the cowboy killer?"

Server: "It's an 18oz Steak cooked to order."

Customer: "Sweet! Don't even cook it. Just walk it in here and show it the fire."
