Joey, "Can I please have a sucker?"
Mom, "No, you already had one"
Joey, "Please!"
Mom, "No, you have had enough sugar"
Joey, "When I eat, the sucker goes in my tummy and when I poop it goes out with the sugar. If I poop, then I can have another sucker?" (Big smile like he has really figured something out)
Mom, "Ha, ha, ha, ha, ha, ha, ha, ha......"
