Karl ("Karli") is the Sackbauers' older child and takes after his father: like Mundl he likes drinking beer, shouts a lot, and uses a lot of obscenities that sometimes get him in trouble. Very early in the series he marries Irma Werner and by the end they have two children, René and Petra. He fights a lot with his sister and is extremely disrespectful to his parents. He drives a forklift but a promotion to supervisor enables him to afford his own apartment.
