Quote from Mitchell in The Long Goodbye
Cameron: Are you actually accusing me of starting this fire just so we could rebuild our hideous kitchen? Mitchell: Uh, accusing, no. but when you say things like "hideous kitchen," it does make me wonder. Fireman: This could be the cause. Most kitchen fires start in the oven. Cameron: Oh, my God, did... did I leave the oven on? Mitchell: Well, it appears we found our smoking "bun."
