The next time I have meat and mashed potatoes, I think I'll put a very large blob of potatoes on my plate with just a little piece of meat. And if someone asks me why I didn't get more meat, I'll just say, "Oh, you mean this?" and pull out a big piece of meat from inside the blob of potatoes, where I've hidden it. Good magic trick, huh?
