we ate your burger and drank your soda all started when Al Luchini volunteered to go get the boys some Burgerville meals. He didn't ask any of them what they wanted, so he brought each of the boys one soda, one cheeseburger, and one small fry. Liam didn't like cheeseburgers or soda, so he just ate some fries, and Adam and Marcus made fun of him. They ate his burger and drank his soda. When they were finished with the meal, Adam and Marcus walked away, leaving Liam to clean up. When Liam questioned this line of thinking, Marcus responded with this logic-filled statement: "We ate your burger and drank your soda, so you have to clean up."
