"Do you know how many calories are in butter and cheese and ice cream? Would you get your dog up in the morning for a cup of coffee and a donut?"

Jack LaLanne is asking a rhetorical question about the junk foods of butter, cheese, and ice cream. He is indicating that these foods are bad for us and must not be consumed in big quantities. He is also making a joke about getting a canine up in the early morning for a cup of coffee and a donut, which is a ridiculous idea. He is attempting to highlight the value of consuming healthy and avoiding unhealthy foods. He is also attempting to make a point that we must not be feeding our family pets junk foods either. Jack LaLanne is attempting to motivate people to make much healthier options when it concerns food. He desires us to be familiar with the calories in the food we consume and to make certain we are consuming healthy. He is likewise trying to advise us that our family pets must be consuming healthy too.
