Relativity

Setting: It's after school. Max is looking for his leftover Captain Crunch cereal (dry) that he didn't finish at breakfast.

Max: "Hey, where's my Capn Crunch. I was going to eat it!"
Dad: "Max, I put it away. You can have it for breakfast but you can't eat it for a snack too. That's too much junk food. You need to eat something healthier."
Max: "But I can't resist junk food."
Dad: "Well if you don't, you'll end up fat and sloppy."
Max: "Well that's a relative measure."
