Cedric Cunningham is a minor character that appears in Old School. He lives a few houses down from Greg, and set up his own lemonade stand with help from his parents. He offers Cedric two bucks to take down his lemonade stand, and he agrees. He then sets up a lemonade stand again across the street from them. After seeing that Cedric's lemonade stand is more popular than theirs, Greg and Rowley decide to start selling NRG Fitness Water.
