2. Most commonly-used sentence when the oven door is open: "You really need to be ELSEWHERE right now." This sentence is good on the cat who insists on being underfoot because he distinctly heard you say you would feed him, the cat who wants to walk into the oven, and the kid who's running/skidding across the kitchen to grab some Halloween candy.
3. I dance. Well. Fairly constantly. But especially when baking.
