Carl is the manager of the local gas station and convenience store, the Quahog Mini-Mart. He has an interest in sexy women and movies featuring sexy women. He also likes women with braces. Carl enjoys passing the time by discussing movie trivia with his co-workers and even his customers.
He is good friends with recurring customer Brian and eventually becomes good friends with Chris after Chris gets a job working for him. He does not get along with Meg, whom he hires and fires in "Movin' Out (Brian's Song)".
He is an alcoholic, partaking in Alcoholics Anonymous meetings Peter attends in "Friends of Peter G". Due to alcohol, he did nothing but stay on his couch and watch movies, giving a thorough film knowledge.
Brian plants a fake lottery ticket at the Mini-Mart with Queen's News of the World album art in order to scare Stewie in "Killer Queen". Carl also thanks Brian for letting him be Yoda in the Star Wars episodes.
Peter and Brian stop in at the Mini-Mart in "Turkey Guys" while searching for a replacement bird after eating it while drunk the night before Thanksgiving.
