Carl is a fat guy who runs the Quahog Mini-Mart. He is Chris' boss and due to his extensive knowledge in movies and TV shows, born of him spending his life, lousing around on the couch and doing nothing, he is good friends with him too. He first appeared in "Mo' Jobs".
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 was threatened by Chris' father Peter in "Baby Not On Board" when Chris makes a sexual remark to Peter and exposes himself to him. To avoid a lawsuit, Carl offers him an unlimited gas card.
He is invited to James Woods' mansion in "And Then There Were Fewer", although whatever motive he had for killing James Woods is never revealed nor does he ever say they'd met previously.
In the song "All I Really Want For Christmas" in "Road to the North Pole", he reveals he wants The Wiz on Blu-ray disc for Christmas.
In "New Kidney in Town", Peter sends him a shoutout on The Price is Right.
He appears in Something, Something, Something, Dark Side and It's A Trap! as Yoda.
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.
In "Tiegs for Two", he attends Quagmire's class on how to pick up women.
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.
Carl can also be seen sharing a bus bench with Consuela as Stewie rides through town under Brian's car in "Family Guy Viewer Mail 2".
During Mayor West's murder trial in "12 and a Half Angry Men", Carl struggles to hide the fact that he can't read.
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.
Carl imitates Bob Belcher and Sterling Archer, both of whom are also voiced by H. Jon Benjamin, for a comedy routine in "Guy, Robot".
He has a crowd scene cameo in "No Giggity, No Doubt".
Carl works at an adult bookstore where Peter and Lois shop in "Heart Burn".
