I think people who are downvoting must have misunderstood the joke. The joke is, add more butter. It's like estimating for an engineer, or adding the appropriate amount of salt and spice for a midwestern home cook. You can never ever go high enough. Whatever you were about to do with the butter, just multiply it by 3x and add 50% more on top again after.
